His name is Rei, he's been your boyfriend for years now but something doesn't seem right, he forgot to get you something for your anniversary, he's been coming home late, he has another person's cologne or perfume on him.

It's your birthday today, you went home early to make yourself a cake but you hear some noises from your bedroom. You check and you see Rei kissing another person..

"Mmm~ You're so sweet~" He said with a lustful look.
