I know the perfect song for this!
Someone posted it back then..It's about a clingy boy who was writing letters to his girlfriend..

But I'm glad he accepted and never ran away ╥﹏╥
This was a good manga to read but so short!
But somehow I didn't feel the "pull" too much of each couple. But since it's just one-shots,then I understand.
The sex was also (for me) portrayed as a means to re conciliate and "connect" with each partner. You don't really need to do it right away yknow hahaha
For me,even if without the sex.Everything would still be better :)
That's just my opinion ლ(´ڡ`ლ)
