Why aren’t we addressing the fact seo-in was sleeping with someone who looked like his adopted brother/villain

idk if i explained it properly actually, so the mc had a flashback where haeyol or wtv his name was looked like "him" and i thought he looked like seo-in's brother, so i compared him and the most recent chapters, they have the same hair, same eyes, same birthmark, and yk how there was a flashback where the mc saw seo-in kissing someone? THAT WAS HIS OLDER STEP BROTHER.
I hope to god he’s not like a romantic rival and more of an older brother kind of vibe !!! Like a rival in the sense he’s just takes up a lot of yw attention, you know???
so what if he's a potential romantic rival???
