I didn't get this feeling from Kwon Jihan *AT ALL* --and I'm wondering how (the hell!) did 17 other people agree with this statement...
If I'm interoperating your statement correctly, you seem to be saying you think Kwon Jihan is the type of person that gets overly emotional over relatively minor/trivial things
-Or-
perhaps, you mean he internalizes
The only thing we see Kwon Jihan get emotional about is Seo

Oops...
-Or-
perhaps, you mean he internalizes the *relatively minor pain* of others into greater pain he feels himself???
Either way, the only thing we see Kwon Jihan *feel deeply for* is Seoyoon--specifically for the horrors he has lived through and continues to have to cope with...
(Spoilers)
Hell, Kwon Jihan is *practically emotionless* discussing the death of his mother--his only relative--and his beloved dogs... He even says he didn't/doesn't feel that much about their deaths...
Kwon jihan is the type of guy who would cry for women's periods
