I know you said it's fine if it's toxic but....these ones are another level warning you beforehand

In this one they aren't completely obsessed with each other but also at the same time kinda are, yk? Either ways it's a good read

I thought that I would have a lot to recommend but it seems that most are just one person being obsessed ... Here are a few I found tho, in varying degrees (￣∇￣") but i also want some recs so i'll follow :3

Im looking for BL recommendations (list r good too) on manga where the characters r obsessed with each other. I don't mind if it's toxic as long as it's mutual ig
I'm just really want something where they r so obsessed w each other it can be considered codependent, kinda yandere so and so, where u r like "wow that's toxic but at least it's mutual"
Thank u(〜￣△￣)〜
