I'm trying to find a yaoi manga/manhwa that I forgotten. The ML is a very promising swimmer. The MC is older and smaller. He seems to not have a job, but he have money since he invested in a failing clothing brand that later became successful. I think MC paid ML to teach him how to swim (I'm not sure about this). One rich guy who knows the MC gave sponsorship offer to the ML for swimming career, however, ML rejects seeing that rich guy as a love rival. And this sponsorship is important to be elected to become a rep for the country at Olympics or some important competition.
The internal worries and monologues when it comes to socialising with others and feeling like an outsider was 100% relatable to me! Esp on the beginning, the story was sooo relatable! But, I never had a bf but I grew to become somewhat ok to be by myself. I cut out toxic friends and don’t try to appeal to other ppl anymore.
