I woke up this morning thinking of a manga I read a long time ago. I really want to check if it has been updated or dropped or you know, what's going on with that manga, but I cannot remember the title and I have spent a couple hours looking for it now but I just can't find it.

I think it might be a shouned ai and I remember it was set in high school, the main guy was well built and he liked gardening. but he didn't want his crush to know that he liked gardening so he wore a mask when taking care of his garden. haha. I think the garden was also at school.
Anyway, he took such good care of the garden that one of the plants turned into a fairy and told him he could help him become his crush's ideal.
I think he was given a seed that he got his crush to swallow and later a plant grew on his head! lol
I know it sounds silly but the main character took the plant before the other guy noticed.

I think it might be a shounen ai more than a yaoi, and I read it a couple years ago, but it's just driving me insane that I cannot remember the title :/

I believe it's Blue Wars. It is indeed shounen ai rather than yaoi.

Thank you so much!
