@Bella Considering Sangwoo and Jaeyoung are friends with benefits, Jaeyoung is going abroad soon, and never vocalised his love for Sangwoo, it's unfair to blame Sangwoo entirely; misunderstandings are bound to happen. Also the fact that Sangwoo acts neurodivergent (specifically on the autistic spectrum, the clues are Jaeyoung calling him a robot, Sangwoo likes to stick to rules and routines quite rigidly and has an aversion to Red hinting at sensory overload and is poor at reading social cues or subtle emotions unless spelt out), and this is his first time in a romantic "relationship/situationship", it made sense how he was trying to rationalise Jaeyoung's leaving to running out of groceries so he didn't freak out over his attachment and intense unprocessed feelings for Jaeyoung, also so he didn't appear clingy nor hinder Jaeyoung's decision to go abroad. It's easy for us to spot stuff and judge as spectators but when you're in the middle of unclear confusing territory and second guessing the other person (Jaeyoung has also acted differently with Sangwoo compared to all his other relationships too), it's not easy to confess and hence misunderstandings are bound to occur.
Hope you can also see things from Sangwoo's perspective too.
