My favourite anime couple is Shuichi x Yuki.
.... Have I mentioned I like yaoi? :D
Anyways they are from anime called Gravitation which was like 3th anime I ever watched and they are soo adorable. I really like the couples when one of them is really hyper and pushy and admits his/her love for the other all the time and to everyone but the other person acts as he/she doesn't care about the other person and fells really anoyed about it in general but then once in a while he/she does something really sweet and then you see how much he/she really cares about the other nd then you just start crying :')
