I think the beginning of that, like the very seed of it was chapter 79, when heejae found out that garam couldn't hate him. Garam basically said that he was doing everything he could to hate heejae because he didnt want to repeat the mistakes he made with youngjo (implying that he had not-so-platonic interest in heejae), and he asked heejae to help him nurture that hate, because garam couldn't do it by himself, and it floored heejae. That continued to chapter 81 when heejae came back from his successful performance (that garam refused to watch) to an empty room, feeling lonely and soothing himself with the recording of garam's jeux d'eau. And then garam saw heejae's chopin and fell in love for real, which led to heejae reciprocating that feeling (though he denied it at first).

I dont get why heejae is obsessed with garam's jeux d'eau i cant remember anything aside before chapter 3 is this a sign for a binge rearead session

You are correct about him falling for Garam with that kiss in chapter 83. Actually this was elaborated a bit further in BDK’s Q&A on whether Heejae fell in love him at the exact the moment Garam recognised the solitude in his music or he already haboured that feeling from the beginning, while BDK encouraged readers to have their own interpretation (she also had her own version), the gist of it is it was triggered by both Garam’s revelation & the alcohol influence. Now to your question when & why Heejea is obsessed with Jeaux Deau, my interpretation is that his infatuation & affection for Garam’s music & him as a person is a slow brewing process. It starts off when he first listened to Jeax deau with the teacher - My guess is that finally after more than 10 years, this is the closest thing he got to hear a sound resonates deeply with him, especially after the lost sound from the dead manager incident & his semi failure with all the past students saga. The second is when he told Naeun to back off & give up the stage for Garam. This defies his philosophy of teaching where he claimed he would never put his personal feelings/business above the sacred music. The third one, you already knew, drunken fiasco. The forth one, which imo is the final nail in the coffin is in chap 88 when he asked for separation living situation with Garam. You have to remember that Heejae put music & its integrity above anything else, he would never, ever let mentor-mentee relationship get sexual when it’s piano involved. That’s why his arc with Yerim stays strictly professional (BDK also mentioned that in her Q&A that in a what-if scenario, if Heejae develops feelings for his female students during teaching, he would drop them instantly lol). So this is crucial to me that the fact he was willing to abandon his very own moral conviction, destroy his life long beliefs to kiss & yield to Garam’s request in order to keep him around MEANS he really really loves Garam, long before he’s being true to himself. Like that boy is truly his one & only love. Obviously we’re in season 6 and I’m dying at every updates to witness because it’s Heejae we’re talking about. It’s gonna be a bumpy ride to that conclusion with him lmaoo.

Thank you for your insight! anyway I'm curious, do you think they will reunite when garam in depression state and no longer playing music or they will reunite once garam make a comeback in music scene? I think first option would be perfect for loving you as a human storyline but second one suits the build up in season 5 about Garam's independence like where musician npc characters say he was so lucky to be under heejae's wings, and journalist asked whether he had a plan to be independent, etc.
