I don't think either of them is acting out of bad intentions. Heejae genuinely believes he's helping Garam get more recognition and grow as a musician. On the other hand, Garam starts feeling like he's not good enough—that he's not as talented as Heejae's other students and only got to perform because of Heejae's help. If they had just talked honestly about it, they could've worked things out. But Heejae expects Garam to simply trust and follow his lead, while Garam keeps bottling up his feelings of inadequacy until they come out as anger. Proper communication is really the key here, and sadly, that's exactly what they're missing.
