Appearance wise you can look at this: http://www.mangago.zone/read-manga/don_t_touch_me_manhua/ They look like brothers xD
Lol, it's okay!!! I thank you for trying to help! I honestly read it for the character and relationship development. Souichi was straight and was jumped by his professor and almost got raped by him. The reason why he was so homophobic, but even after all that, he slowly developed a relationship with Morinaga. Their relationship went through so many hardships, and Souichi faced so many thoughts and feelings that were so unknown to him. Morinaga helped pull those unknown things out of him. It's such an amazing development, and the best part is that it's not rushed!! I just truly love how they got through hurdles and how Souichi responds to Morinaga now, compare to how he responded to him during Challengers!!! Though to be honest, I skipped over Tomoe's story to go straight for Souichi and Morinaga. I also read The Tyrant Falls in Love first...
Anyway, thanks for trying to help me, I truly do appreciate it!!!!
I recently found a webtoon, that is loosely similar to what you are looking for. I just remembered your question, so I thought I'd post it.

It has the homophobic uke but the development is much slower and the uke is often an inconsiderate jerk. But maybe you want to give it a try. I personally like it.
Can anyone tell my any yaoi manga that's similar to The Tyrant Falls in Love? Or to it's uke Souichi Tetsumi? Please!!!! Thanks in advance!!!
