I actually went to like it I agree with you wholeheatedly, my bad
Yep, it was pretty poor show of Jaeha to project his own insecurities onto Eunho, but at least it has been depicted in a more realistic manner, and Eunho is strong enough to question Jaeha rather than accept his insecurities as his own.
I guess also, in terms of LGBT equality, major progress has been made around the world in terms of legal rights and social acceptance within a relatively short period of time. In the decade or so since Jaeha first got together with the man who wanted to take him to Paris (can't recall his name), things like same-sex marriage have became the norm within most of the developed world, as well as other progresses. Eunho's home environment as a teenager was far more supportive that Jaeha's, and the world he grew up in was also much more tolerant.
I understand all of Jaeha's fears that's why he won't commit to Eunho. Jaeha is afraid of the backlash that Eunho will receive about being gay. But what he fails to remember is that Eunho is an adult now and not a mere child anymore. Eunho can make his own decisions.
