Your description reminds me of this - https://www.mangago.zone/read-manga/naraku_no_hanazono/ - however they meet in a forest, not on a tree. There is a buried body, but also not under a tree.
Also, it's a really dark story with themes of CSA and incest, so just be warned. If this isn't it then sorry!
naw , its actually that, and i found it yesterday and just forgot to update this, thank you very much anyways o(〃＾▽＾〃)o, i was also quite suprised when i saw that it ended already.
Theres this manga that i have been searching for since yesterday T.T, its like an shoujo ai but not really so theres this 2 girls(?) that met up on an tree and is meeting there frequently, i think they also add more characters not sure and iirc there was an plot twist where an ~~[ded body]~~ was buried under it?? one of the mc family is gud(im pretty sure) and the other one is cooked(only dad left and is not in the right mind) last time i read it there was like 11 chapters around last year, for the title i really not shre i think there was an "tree" in it though. thanks in advance! （￣へ￣）
