I've been thinking his Jinx started from someone on the agency he signed in probably it was initially offered to him that he can request someone to have s€x to cool off and it becomes a habit that he claims it now as a Jinx or it was his coping method as we saw his backstory [and Heesung got to know about it because he thought Jaekyung might be a match for him but was a complete opposite and he never told anyone about it ]
Then probably at some point when the conflict between Jaekyung and Dan was all good and they got together, Dan will most likely make Jaekyung realize he was just too good to have a Jinx like that.

To be fair, it's sad how she experienced that kind of situation but it wasn't even related for what she saw and it doesn't even concern her in the first place. It's a good thing that she cares for Mr. Kwon but she's making a decision like she has every right to do so especially setting him up on dating apps— if it was me I'd be so angry. That's literally invading his privacy.
All of these shizz just because of a damn reputation.. what are they stuck in the earliest days of the school to which these dramas started? To continue and pass Kikyo's generation without even considering how are the new students are on Chidori, to think they're still some kind of virus growing and spreading as delinquents is so out of touch. How can they be a good example if their feeding the girls such lies without a concrete proof of reality.
Anyway, this is such a ridiculous chapter. Shoutout to Subaru and Madoka for stepping up!
