Yaoi manhwa

Looking for yaoi manhwa about the ml picking up the mc and taking care of him at his house. I think the ml is either an author or artist and the mc is still a student. The ml has either blonde or light colored hair and the mc has brown hair which is quite long so he likes to do a half up/down hairstyle. The mc develops feelings for the ml but the mc looking like the ml’s past lover he refuses to start a relationship. Out of desperation the mc suggest the ml to use the mc as a replacement for his past lover. This is all in colored btw, unsure if it started off as black and white as first and then transitioned to colored.
