Hi! I'd like to find a couple of yaoi mangas, but I remember very little(

1) two kids met at school, one of them modeled for the other's drawing...Then the artist had to move and they met years later in art college...

2) a professional model worked for an artist (or maybe a photographer), and i think slept with him to give him inspiration... but the artist couldn't draw anything and was constantly angry... And the model decided that he is no more suitable and accepted an offer of another artist... But the first one didn't let him go, naturally))

Sorry if these descriptions look lame, I hope that at least someone will understand what I was trying to say)
Thanks a lot in advance!

For the first one, I think it's Bara to Yaban.

That's it!)) Thank you verrry much!)))
One more left to find)
