It’s a Japanese BL manga with two men in the lates 30s or early 40s
Basically they have been friends their whole life and they decided to get together since they are both singles.
They are both office workers.
The seme has dark hair and the uke light hair
I remember I read it it on MRM but I can’t find it there
I like that they brought back the ED plot. In a lot of BL where a character has ED, it’s always the whole “oh love cures all and save the world”
But here it’s an actual condition clearly influenced by the mc’s mental state and he might actually need professional help
omfg i didn't mean to leave a downvote, i completely agree! im gonna let the story marinate again though as someone said that it'll be on hiatus after chapter 55
