@Popeye i think you are making it sound more romantic than it actually is. Jaekyung had jinx partners and doctors before Dan, they only left because they couldn't stand his personality (and probably weren't blackmailed with money...) not because he didn't trust them. So I don't think that just his reaction would prove that Dan was "special" to him.
@Claire Having trust in a person does not necessarily mean considering them romantic or special compared to others. But in the chapter about Jaekyung's birthday, the coach told Kim Dan that Jaekyung also felt that his optimal health was due to Kim Dan's professionalism, as if JK was also a minimum "grateful" toward him but did not know how to express his gratitude because of his personality. I simply meant that JK trusted Kim Dan as a physical therapist and jinx partner. However, having said that, there is no denying that JK may have some interest in Dan, which he is not yet aware of or does not want to admit to himself. If at first it was simply a relationship of convenience, over time both have imperceptibly grown closer: JK has totally let him into his daily and working life, put himself totally in his hands. Then again, if he hadn't had the slightest interest, he wouldn't have committed that unpleasant thing with Heesung, or he wouldn't have come to involve Kim Dan in their sexual sphere, where he also began to take Kim Dan's sexual pleasure into consideration (I could go on). Quite simply, JK puts his work as an athlete above everything and everyone, even himself, and even if he is not familiar with feelings, I think it is undeniable that he feels hurt by the situation and by Kim Dan: and I repeat, having trust does not necessarily mean being romantically attached to someone, it can include so many other facets as well!
