Searching for a BL manga

IMPO NOTE:
I READ IT ON MYREADINGMANGA, NOT MANGAGO SO IT MIGHT NOT BE HERE.

GENRES:
It's a supernatural BL, I think it was also a slice of life and comedy but I'm not sure. I don't remember if there was any yaoi scenes or not.

PLOT:
MC and ML start off as strangers. MC is connected to the ML by a curse; their lives are basically connected where if one of them were to get injured in any way, the other person also feels the pain (I don't think the other person will get wounded though).

There's a scene I remember where they're in a small restaurant or cafe and they run into a gang or a man with a gun. ML is shot in the heart and starts 'bleeding'. In actuality it wasn't blood and it was just coffee or smth because he put some mug in his pocket beforehand.

COVER/THUMBNAIL:
The cover only had the MC in it, no other characters. He was standing off to the left and I think he had a bike with him. The setting was like a non-busy marketplace/street. There were some scraps on the ground too I think. The colours were either normal colours that were just dulled down, or a variety of greens.
