I'm looking for a fairly old manga that I read five or so years ago. It's about a bottom who has a crush on his friend, and a top who is the younger brother of said friend. It begins off with that friend getting married and the top's involving the bottom in some non-consensual sex (which involves bondage - wrapped his hands with a tie or so), I believe. Other details would be that the top caught the bottom, shown in a flashback, smelling the shirt of the bottom's crush, and the bottom avoided his crush ever since; that the bottom dated his crush later (but chose the top in the end, naturally); that the top is in high school whereas the bottom has graduated, and dominates him in height. I have a hunch that the top's name begins with an A and the bottom's with a T, but I may be wrong.

Many thanks if you know the manga which I'm thinking of.
