Doumyouji Gai is the secret route that isn't so secret because he appears as a common event for everyone. One day around November, Satsuki tells Kyoko that there's a guest in the living room that her father wanted her to meet. As Kyoko goes in, Satsuki mumbles 'shotas are also nice', LOL. The guests are old friends of the Himeno family, Doumyouji and his son Gai. The Doumyoujis have been doing business overseas for a while now, so it's been some time since they've returned to Japan. For the 10 year old Gai, it's his first time meeting Kyoko or at least the first time he can remember. Actually Kyoko has met him before as a baby and apparently has also even changed his diaper, which embarasses the young guy. Gai is going to attend Tokiwa and his father tells Kyoko how Gai was excited to be able to go to the same school as his fiance, making Kyoko ask who? when it's Kyoko. So Kyoko's father had, at one point a long time ago, a rough patch with the company and it was Gai's father who helped him out of it. That's why Monji feels indebted to Doumyouji that he, over drinks, even offered his daughter's hand in marriage to Doumyouji if he ever has a son. Monji never told Kyoko about it so of course she was shocked to hear about it from Gai, who has been told about it and it seems he was actually excitedly expecting it. The parents say it was just some promise they made so the kids don't have to abide by it. This news makes Kyoko relieved, since having a sudden young fiance is too much for her, but it shocks Gai making him question if Kyoko wouldn't want to be engaged to him, with eyes of an abandoned puppy according to Kyoko even though she can't see them, that's exactly what she said lol. Unable to reject him, Kyoko seeks help from his dad but he's all for having such a pretty daughter and Monji is fine with it as long as Kyoko is. So it's decided that Kyoko and Gai will go on dates and the real shota option is opened.
Actually if Kyoko messes up and doesn't get a guy by Christmas, which really disappoints Satsuki btw, the game automatically goes into the normal ending. The normal ending is a Christmas date with Gai who is really interested in Kyoko and asks for her to wait for him to become a great man.
When aiming for Gai, for the first date Gai shows up with a bouquet of flowers that's too big for him to hold that it looks like a bouquet with legs, and Kyoko and Satsuki find this so cute. They go to the mall to get to know one another, but a purse snatcher runs by and Kyoko has Shinnosuke take care of the guy. Seeing this Gai starts admiring Shinnosuke for his bravely and asks Shinnosuke to make him his disciple. Shinnosuke gladly accepts Gai as his disciple and even has high expectations for him. The next date Kyoko goes visit Gai when he's training in the mountains with Shinnosuke. There she sees him training martial arts and finds the little guy a little cool that she dokis a little. When they take a break, both Shinnosuke and Gai for some reason change back into their normal clothes, they say it's because as gentlemen they can't present themselves to Kyoko all sweaty so they changed, more like the staff didn't make the sprite just for this one scene haha. Shinnosuke reveals to Kyoko that Gai has promise but he's seriously lacking in confidence so Shinnosuke wants to find some way to boost it some time soon. The date after Gai visits the Himeno mansion while Shinnosuke and Satsuki are out. Burglars somehow make it into the mansion. Gai and Kyoko are tied up in the living while the burglars look around the mansion, and Gai is completely terrified which makes Kyoko pity him. At times like these Kyoko has a secret transmitter to contact Shinnosuke, but it turns out this is all part of Shinnosuke's 'plan' but the burglars are real. Kyoko unable to reveal the cruel truth instead encourages Gai to use his training and somehow save them. With words of encouragement and one of the many weapons Shinnosuke has hidden around the mansion, Gai suddenly goes wild by first freeing himself, then using a taser to incapacitate one of the burglars while threatening the other with another weapon. Kyoko seeing the little guy take down the criminals starts feeling that he may be going just a little over board tries to stop him, but he claims it's for her sake so Kyoko can't say otherwise. After Gai has taken down the criminals, Shinnosuke shows up to applaud Gai for a job well done. But the series of events makes Gai think that Kyoko and Shinnosuke did all this just to make a fool out of him and runs home crying, even returning overseas.
It's 10 years, Kyoko hasn't made any improvement in the love department since then, probably because she's always felt a little guilty from what happened. One day upon returning home, Kyoko is greeted by a Satsuki in panic begging Kyoko to wear the wedding dress if not her collection is in danger, lol. Seeing how desperate Satsuki is, Kyoko wears the dress then goes back out to find Shinnosuke beaten up. A young man appears sitting on top of Shinnosuke and greets Kyoko saying long time no see, it's Gai!! After the humiliation, Gai went back overseas trained like crazy and became worse than Shinnosuke as he's also a bit of an S. Gai beat up Shinnosuke because he completely thought that him and Kyoko were together so he wanted to snatch away Kyoko, but since it wasn't the case he'll still just take her. An option appears for Kyoko to accept or refuse but either way she can't refuse, hahaha.
Glass Heart Princess was really fun. I repeat it was really fun!! I honestly didn't expect all the parody, the breaking the fourth wall, the tsukkomis, and the whacky characters with their whacky plots. I loved this game! All the characters were great! Each had a personality that was really fun! The interactions between characters were fun to watch and Kyoko was also great at role of tsukkomi when needed. The game was colorful and pretty. There were plenty of CGs some really awesome ones. The events were unique to each character so nothing really repeats. I highly suggest going through some of the choices because some of them had some really interesting and funny reactions. The game even covered what happened if they failed the cultural festival event, Kyoko ends up singing and dancing on stage instead after Satsuki had her learn the songs in her sleep hahaha. As I said in the beginning, Satsuki is awesome! I really hope they make a fandisk for this game, because it really deserves it unlike some other games coughhakuoukicough. The system was simple except for Shinnosuke but with prior knowledge of this it's fine, the text isn't too complicated that someone with a decent understanding of Japanese wouldn't be able to understand, the game isn't too long in fact since I like it so much now I feel like it wasn't enough, the characters are lovable, the stories are decent, this game is definitely worth playing.
