As title says, suggest any manga/LN/anime that is about a romantic relationship between two friends and is free of love triangles. I hate Love Triangles so... recommend something sweet and wholesome as long as possible.
This thread can be a good list for those like me, just ignore my list, Thank you for your help.
this was hard lmfao i guess i havent really read a lot of "just wholesome romance" stories, its all plagued with love triangles
these are just what I could think of
Arasa Dakedo Hatsukoi desu
just wholesome not between friends though
Kawaii Hito
another just wholesome story :P
This may or may not be helpful but I suggest using the browse feature or just click these links!

You can adjust it if you want to using the advanced filters :) e.g you want to filter more genres/tags, etc.
