This game has been released recently and I must say it's better than I thought it would be =D
The premise is having a love affair with your own brother, however, the protagonist and her brother are not blood-related so it's a "safe" enough game ^^;
Also, although I do not have some sort of brother-complex, I've been enjoying the story a lot because the game seems to take itself very seriously... once outside of the tutorial course XD
In the game tutorial you're greeted by Johannes Gilbert, a darker-shorter-haired character, who explains you all the basics from the gameplay, which is pretty straightforward when you're a seasoned otome in the field of visual novels.
You're also given a login bonus everyday, in which you gain 10 gacha points per day. Gacha costs 300 points each spin, however, it's very easy to collect gacha points in here because of the simple action minigame you play - it costs 10 stamina each play and I hardly walk out of it with under 10 gacha points.
Besides gacha points (called "Capsule toy point" in-game), there are Coins (the cash currency), which can be gained through accomplishing certain tasks, such as registering your e-mail as your login and posting a tweet from inside the game's interface. Yay for being able to buy cash items without actually spending real money! \o/
So you - the protagonist - is the daughter of a really sad woman who marries men solely because of their money. One night, you're in a high-profile party and spotted by a wealthy man, who gives you a money offer if you agreed to be his woman, but the clever protagonist obviously refuses, because she despises the way her mother acts and she is very different from her. Enters Mike Jones (the brown-haired character sporting such a nice cleavage), your current stepbrother, who misheard the conversation and thought the protagonist were going to accept the man's offer, immediately badmouthing her - next morning you find out he traveled overseas and you never had an opportunity to make things clear with him... until 5 years have passed, when Mike comes back and, surprisingly enough, kisses you withought prior warning, leaving the protagonist confused because of mixed feelings as to accept Mike as a brother or a lover, specially when he seems to already have a fiancée!
This summarizes what the first chapter is about, and I really like how the story is developing itself so far, so even if you do not feel attracted by the brotherly-love, please give this game a try anyway, because the plot is thickening each passing day~
