finding out how your parents ended up like that, do you actually think a person can think straight? especially when he thought it was an accident.... right now everything to Sejoon is a shock, as you can see he really doesnt blame Taehoon but he was hurt how Taehoon cowardness gets the best of him instead of facing Sejoon (tbh I really thought Taehoon is coward right from the first we knew he had a past with Sejoon and push him away, I get a feeling that he is really scared to take/look at the guilt he is feeling) .....Sejoon-he wants revenge for his parents not exactly he is hurt by Taehoon
