Hello! Does anyone know the bl manhwa where the mc has a male friend who faked a blind date for his friend to make ml jealous, and showed up himself wearing a red winter coat??? I read it a long time ago so I forgot the title, I wanna re-read it since I remembered it was quite good. The friend in the red coat is always with mc, he even wore the red coat at their university where ML saw Mc and red-coat friend together and didn't recognized it was mc's friend.
Do you guys know this one? https://www.mangago.me/read-manga/a_relationship_that_should_never_be/
If yes, can you recommend something that's similar to the seme here? I just really liked the seme's appearance and vibe here.

So I was reading this manhwa about a high school boy (mc) in love with his senior, but the senior is straight. Senior has a younger brother (ml) who is the same age as mc. The brothers really look alike, uh, brown/blonde hair. Ml has piercings. Mc is black haired. The artstyle is really unique, (the faces are quite lacking in emotions). So mc and ml spends time together, mc moves on and likes ml but he overheard in the clinic that he is dating some other girl from another school which turned out to be a misunderstanding. Mc avoided ml, then mc asked senior for advice in his house, ml comes home and sees them together, assumed that mc still likes his older brother (senior). I forgot the title since I marinated it for a few weeks. And I forgot to add it on my reading list.
Never mind, I found it! Fever is the title if ever anyone got curious.
