no youre so right. and bc theyre not blood related it makes sense. also with Jaewon being the controlling asshole he was, he probably figured out that Seo-in was starting to develop feelings for Yeongwoon and vice versa. Jaewon probably thought that the best way to fuck with both of them was to have Yeongwoon catch Seo-in kissing him. It’s weird and manipulative af but it’s quite literally Jaewoon’s MO.

that's a good plan tho but at this point it's going In flashback so how he could've kissed Jaewon and imagine yeongwoo??? So even tho the clothes are different it's just because it's a dream? Wait Yeah i think i remember yeongwoo saw someone kiss Seo in in the story or am I tripping?? I'll have to just read this again I guess
i have a feeling that Seo-In was actually kissing Jaewon in the last bit (chap. 36) but he only imagine Yeongwoon, pay attention to the clothes
