y'all pls help me find this bl

I've read this before but i forgot the name. It's a short manga where the bottom is super obsessive with the top like he keeps all his things and displays it on his room. The top is just as obsessive but he kept pretending/denying he didn't like how obsessive the bottom is and something happened (i forgot it, i think it was abt the bottom knowing other men idk) and he absolutely goes ballistic cuz he's super crazy jealous and they fawk and he started to admit taht he's just as crazy for the bottom. I feel like this is a vague description but it's all I can remember with my fckass short term memory so I hope someone knows this.
