Please help :3

I'm looking for this manwha this description is the only one I have please help...
I remember this scene with this one character. She was trans and was friends with the main character. One day while smoking outside the main character sees the women stumble out with a hammer and ask for a cigarette It was implied she killed someone moments prior and since then she comes by every once in a while to talk about life but they never would ask questions further than basic things One night she comes out of the blue while the main character was sick and after a night of drinking she only asks for the main character to “hold her hand” for the night. Without questions she does and the next morning the woman is gone without even a note
