Naw I highly doubt that considering Seo-in still has his memories with him from the past.And you only reason he treats the MC that is prob cus hes still mad or confused why the MC left him cus if you know he considers the MC as his “first love.” Also Seo-in and his twin brother both have moles under their lips but Seo-in has a Mole under his eyes.And lit from the info given to us so far the MC and the other twin got no chemistry other then the fact he beat his ahh.And bro clearly has trauma.
Also I have another theory.
What if the reason to Seo-In’s Twin’s death is becuase Seo-In killed him thats why he barley seemed fazed while visiting his grave.Or the MC killed the Twin thats why he ran away and booked and nobody knew.But I doubt the Mc killed the other twin considering the fact the twin prob died AFTER he left.

oh actually now i think there was a fight between then, maybe that's what makes yeongwoon uneasy... but i checked before and seo-in mother said in a chapter that they have eaten together in a restaurant when they were in college ... so his brother died after yeongwoon left ...
since his cousin blames him, i think maybe seo-in and his brother fought and after that his brother got some accident and died.
the famous brother died so their parents made the asshole brothers switch places with him, that's why he's acting like that towards the MC
