Help me find this

There was this bl which is omegaverse I'm pretty sure and the main storyline is that that the ml is like a teacher on hairdressing in like a uni or college idk and his best friends brother is interested in hairdressing as well and he has big man boobs and he's a bit tan and when they first meet I think his best friends brother shoves like shoves his head into his man boobs (?) and I remember the last chapter i read was where like the best friends brother apologised for it with a gift bag but he put his pheromones on the item in the bag but the ml doesn't know his best friends brother is an omega so he thinks those are his friends pheremones
