PLS Help me find this manga!

I have no pictures of it, but if I remember correctly it was about a gay boy who fell in love with a straight guy (ONE OF THE MOST COMMON BL TROPES!) and then he proceeds to confess his feelings to the straight guy, he didn't reject him but instead they've got into an arrangement of sorts; they decided to meet up ONCE every year, a few years forward when the oh-so-awaited meeting date came around *poof* the straight guy reciprocates his feelings!

Then, they went off to meet up with their highschool friends ≧∇≦ (and that's all I've read so far).

Thanks in advance!
