SATURDAY
Dan-Han hesistated stepping out of his car as he parked in front of Eun-sun's apartment. He wasn't sure he was making the right decision but he had no other choice.
He had decided if it was too difficult to tell In-Ha the truth verbally, he might as well show him via actions. Actions suited his personality more. He couldn't imagine trying to explain the whole situation to In-Ha. In-Ha's reaction was probably going to make him feel bad but he still wasn't going to lose his girl, he'd take the risk.
If he'd let In-Ha tell Eun-sun about his feelings for her, it was going to burden her and knowing who she was and how she valued In-Ha's friendship he knew she was going to feel sad, as confessing his feelings was going to complicate their friendship and might even break it. It was better if it remained unsaid and she never gets to find out about it.
