Help finding a BL please

Struggling to re-create my read list.
Sorry in advance that I can't remember much of the plot other than:
It's a friends to lovers. Red haired, goofy uke and a more straight-laced black haired seme.
I think the art style was unique and looked more drawn than digital.
I think there's either a part 1 and a part 2, and no smut til part 2
I THINK the black haired seme was gay, and the red haired uke originally straight. I think it is the red head who pursues the seme.
And I know this is generic, but in the 2nd part (where they now live together as uni students) I think there's another seme who shows interest in the uke. There's a confrontation scene where original seme is angry that the uke is with the rival seme, and this comes after an argument they've had. I think the rival seme had kissed the uke.
Sorry I know this is all generic but I cant find it and i'm desperate!
