You mean this one ? (This one is a manwha but there is also a manga of the same name here) https://www.mangago.zone/read-manga/dive_yeonpil/
Love or Hate - its a love triangle but the mc's opinions and views, his inner thoughts all of it are expressed quite wonderfully throughout the story, dive deals with inner conflict regarding his passion, this one deals with inner conflicts of his own feelings and what's logical

Fate Makes No Mistakes - no getting over inner conflicts or something but the mc has a tragic backstory and ml helps him by loving him, it's beautiful as well as interesting.

Here U Are - mc deals with inner conflict of loving the ml but at the same time wanting him to not be affected by the societal outlooks on a gay couple

samee those are my top favs too!!
And gosh i am so happy that you think the same about love or hate, its hated so much simply for the love triangle and step brother thing which I can see how frustrating it can be to read but it's so much more than that, Lee Haesoo's personality was expressed so realistically and each and every aspect of the story could be analysed and explained due to how well each character's perspective is focused on. I'm sooo glad that you appreciate it too!!!! (っ˘з(˘⌣˘ )
Y'all know any manhwa like Dive??
