I mean like.....
You know why he felt that way tho.........
Its because in a way it reassured him that he could have a chance........
Its not because he actually wants to see him suffer.......
Really?!? Because I find it twisted no matter what
Yes, it kinda seems like nobody is "right" here, but just being themselves they are helping each other. A thing that Haesoo and Joowon could't do by themselves alone (they were just kiling each others!)
Well, let me put this into perspective.
Based on your name Im going to assume that you are a girl.
Now imagine that you are crushing on this guy/girl (I dont discriminate)
Now the person you like tends to talk and flirt with others.
Naturally if you really like the person you start to feel jealous.
Couples in relationships also get jealous its a natural feeling.
Taku felt jealous and when he saw Haesoo cry he felt reassured that he could probably have a chance.
That feeling is also normal. If a guy likes this girl who happens to be dating then, naturally when he sees her cry from the pain her partner caused he would feel mad and like he has a potential chance with said girl obviously after she recovers.
Finally I get why Taku never convinced me 100%. He doesn't seem to have a heart. He simply try to say and do what he thinks other people like, he even said he was happy to see Haesoo sad. Well..this is too* twisted for my taste. Bye Taku xD
