Your comment on outing someone, 2 comment above this comment have made a well articulated point refuting yours.
For the 'sorry i was worried.. ', this shows a lot about their real problem now, lack of communication.
-mixed signals (inwoo is insecure, but that doesn't mean he should lie)
-adjusting a meeting with inwoo's mom behind his back
-both of them not contacting at night eventhough they worry about eo
You get my point. Anyways, not all relationship would have 2 people directly sitting down to talk after an argument. People have different personalities and some are less confrontational, but there are so many ways to communicate and this couple haven't found it yet.
fuck inwoo like actually fuck you.
outing someone then throwing "sorry i was worried about you all night" when he didn't even bother messaging him
