■Characters■

◇Reika◇

Reika is one of the most popular girls in school and the top of the class. When you find out she is going to be your new stepsister, you can’t imagine anything going wrong. But once you get to know her, you realize her persona at school is a sham. The Reika at home is sadistic and cruel. Can you save her from herself?

◇Seri◇

Seri has been your best friend for years. Though she’s usually busy playing whatever sport is in season, she prefers to spend her time with you at the arcade, where she holds all the high scores. As you try to protect her from Reika, you realize your feelings for her may run deeper than just friendship...

◇Yoshiko◇

Yoshiko is a sweet, quiet classmate who you’ve recently become friends with. She can always be caught in the courtyard reading, and the two of you bond over your love of books. Problem is, Reika has tasked you with spying on her, but the more time you spend with Yoshiko, the closer you become…

The story is fire and I like the graphics, all tho I hate that the premium options cost but I'm ok with it all tho I do recommend that the points get doubled or maybe thay can get upgrades for the points to get multiplyed or maybe a upgrade so how much points you get is how many gems you get. I would give it a 5 but cuz of the point problem I didn't. Also the adds have stopped. At a certain amount of days. On mine

Good story-wise and good art, but a lot of choices is locked behind gems which is really disappointing. I don't mind a game having in-game purchases but to have it being essential to enjoy the content is utter BS. It is still a new release so I really hope they make it so that one can watch a simple add and get some gems. Then I can maybe enjoy the content instead of skipping past every single choice with locked behind a stupid money-wall.

For real tho genius didn't expect this from a top tier game maker as you(for me atleast).. I think the last time I played one of your games was like an year ago. The reason being, the watching ads for points not working!! it just says there are no videos to view.And that is something which I believe is making the game unplayable for players like me that would like to watch some ads and get a few rubies (repeated a few times and we get to make 1-2 premium choices) PLEASE BRING THE ADS BACK!!!!!
