Hajin has also hid his feelings.
On your number two, Hajin left his phone at home but he lied to Hangyum about it. One your number three Tapas has changed the dialogue. It is kind of the same but not. It is clearer in the Korean, he knows nothing happen.
You may want to edit your message and change Hajin to Hangyum in your last paragraph. I think you mean
“ I know Hangyum lied about”.. then Hajin
I don’t think it is Hajin being an asshole. He is just tsudere and He is just dense. Hangyum in the past until now has made it his feelings clear and Hajin just does not understand it or over looks it. Yes your right with anything else and yes if both of them actually talked about things all this could have been avoided. With Hajin revealing his feelings and really taking Hangyum feelings into consideration.
For feeling hurt. Hajin has also lied to him numerous time about things concerning Jahee. Also it doesn’t help that there’s a big misunderstanding that hajin and jahee slept together. To me it seems like Hajin has never really taken Hangyum feelings into consideration at point during their relationship
1) when Hangyum asked hajin had he been in any other relationships he straight up lied to his face and said no. Even when jahee return and hajin realized all three of them would be working together he still made no effort to tell Hangyum to avoid any misunderstandings in the future.
2) on Hangyum birthday when Hangyum pretty much begged hajin to go on a date with him because he had something important to tell hajin what does hajin do he runs to his ex’s side and stays with him all night not even bothering to explain or answer any of Hangyum calls.
3) lastly he gave jahee the the prefect opportunity cause a big misunderstanding by drinking with him And even the morning after when he thinks him and jahee slept together he’s rather nonchalant about it.
To me hajin is the bigger asshole of this series. I know hajin lied about who he was from the beginning but at least it was because he was afraid that the only person he truly loved hated him. Maybe if both of them actually talked about things all this could have been avoided.
Sigh rant over
