I once read a Shounen Ai/Yaoi manga that I really liked, but I can't remember the title.

I remember that it was about 4 volumes long, about two friends that went to a boarding?school. They fall in love, but realize that being gay would be hard in the real world. I believe one of them has a family that would be against it? Anyway, one of the guys runs away from school and the other follows. It rains and then they are alone in one of their families houses. They finally have sex then. I do believe that was the last volume.

I believe the boarding school was on some mountain, in the woods, far from the city. I know it sounds really vague, but does anyone now the name of the series?

So;

• Yaoi/shounen ai
• about 4 volumes long
• 2 boys in a remote boarding school
• contains a sex scene which takes place after they take shelter from rain

Probably not since it's only a volume long but something similar happens in Shinyuu Henjou!

No, that isn't it, but thanks anyway! I know I'm being vague...

So, I did a quick search and the only thing that kind of resembled your request was Takumi-kun Series. There's something about a boarding school away from the city "in the mountains" and some family drama but I haven't read the manga myself yet so, I can't tell for sure. It's still an ongoing series but it's been scanlated up to volume 4.

It's the Art of Time, it's the Art of Life--
Of the player and the craftsman,
Of the writer of songs, of the creator of love,
Of those who will follow, of those who led,
There's no other way in the world ahead ♥

No, that isn't it either, though it looks interesting. Thanks anyway!
