I want to find a yaoi I've read before. it was omegaverse, omega x alpha. Omega is a high school student, he meets per chance his fated pair his alpha. But this alpha is.. in grade school or something. He's very young.
So omega tries to meet with him while pretending to be normal without having any kind of weird relationship, but he has to take a lot of suppressants... and it doesn't really work cause he's in heat a lot of time after meeting him and even when he's with him sometimes.
The mom of alpha discovers omega, and to protect her son she sends him to his grandmother so that he can't meet omega, who's always in a sexual state when in contact with her son so it's innapropriate. Both omega and alpha are very sad but they know it's for the best (especially omega who's older), and they have to wait until alpha is hmm, maybe 16 or something. Then they meet again and finally go out and have sex.
Omega was blond and white skinned, alpha had black hair and also white skinned.
Does someone know this yaoi?

I want to find a yuri I've read before. If I remember right, the art was very shoujoish. One "girly" girl falls in love with a person she thinks is a man bit in reality is just a "boyish" girl, and confess or something. The boyish girl doesn't take her seriously at first and ask her out (maybe for a joke?) but the girly guy takes it seriously and is very happy. The boyish girl feels bad cause she realises the other girl think she's a boy and can't tell her the truth cause she's embarassed, then later girly girl realises the truth but still feels attracted to boyish girl, and they go out for real.
It wasn't very long, maybe like 5 chapters, girly girl had sort of brown hair (maybe even red) and boyish girl had black hair.
