Jimin is an author of perfect characters
He always constructs these lovely men, with personas and quirks he adores but will never see in a real person
Stuck in a writing block, he seeks out light to color his grey mind, he sees a man at the piano bar, a man playing piano, a man with nice hands, shagged hair, with cracked lips but a nice smile playing piano, looking right back at Jimin.
He goes out searching in Seoul, and Seoul guides him to an answer he never asked for.
^basically Yoongi is a lot like this one character Jimin wrote about, and Jimin kinda dies on the inside
