As I mentioned before, it's a game where you will get to raise twins, or one of the twins (with you being the mother)
More info came out, and we now know who the twins father is:
he's sexy and... funky. lol I think he's an archaeologist, and thus the getup. (but the boots...! XD)
we also find out the twins' personality, and if you visit the official site , you'll get to see this:
Raito (the one on the right): "I'll protect mother, because I love her very much!"
Fuuto (the one on the left): "I want to hurry and grow up... because I want to marry mother" -> *faints* xD (well, he's but a child... so that's an innocent comment ^^'')
The twins are pretty much opposites (as can be seen just by looking at the pic)
Raito, the older of the twins, is an extrovert. He's a mischievous little kid, and likes sports more than studying. He's pretty active and cheerful, and has innate leadership abilities as he stands up for what he knows is right. It's said that he resembles his mother.
Fuuto on the other hand is an introvert, a shy and withdrawn person who likes studying more than sports. He's timid, but is really kind and mature (so to speak). He's a crybaby, and a mama's boy too. It's said that he resembles his father.
I still haven't played the game but I already want to huggle and cuddle
