So the Manga/Manhwa/Manhua idk has a blue haired bottom and a blonde top. I think he was blonde? I'm sure he was blonde.
As far as I remember the top was drinking alcohol abd the bottom comes to his place to check up on him. The bottom founds him lying on the ground with blood that turned out to be wine.
Another thing I remembered was that the top asked for advice from his friend and got himself a woman costume. Which got swapped because he was supposed to get the policeman costume.
I think the top and the bottom went to the bottom's old house which he grew up in and it was abandoned? And they visited the grave? Or was that another manga?
