Please help me find the yaoi manga

Please help me find this yaoi manga. These two guys confessed to each other in middle or high school and had been together ever since. At first they were happy just being with each other, but later on they become really really inlove and almost obsessed with each other. Time skips and they're already adults living together. Uke receives a call and is asked to hangout and drink. Uke arrives at the bar. His boyfriend is there and their school buds. Uke sits besides seme and their friends start complaining on how seme always hogs the uke. They then talk about how seme-kun is an ikemen and that they're jelouse of him cos for sure he has dates and all that shit. They then tell the uke how cute he is and that they wouldnt mind dating him. Seme low key explodes and tells them that him and uke-kun will be going home. Upon arriving home, seme-kun turns yandere mode and punishes his uke-kun and asks who he belongs to. Uke-kun says that he belongs to him and also goes yandere mode. I think its part of a manga with multiple stories.
