Suddenly got the urge to reread this one shonen-ai manga I've read about a world where kisses are valued more than sex is. The problem is I can't remember the title. What I do remember are the following characteristics:

. the cover art was really water-colorish, I think one of the leads has green hair and it looks fair blond on the bnw manga panels. The other lead has blond hair.
. The art style made the characters look like 12 year old children but in reality they're 16-17 or so. also the setting was in Europe since I remember the characters travelling to a France look-a-like in one of the chapters
. Since kisses are valued more than sex is, the protagonist's father has a husband but conceived his child with their best friend who was a woman. Pretty sure it ain't a poly relationship though and I might have gotten some parts since it's been a while since I've read this
. and I'm not sure if this helps but there was a scene where the two leads go mushroom hunting

Shinkuu Yuusetsu maybe?

Thank you! That's exactly the manga I'm looking for
