The gist is that the professor accompanied Garam to his performance and the 1st leg of the tour in Tokyo he said both Compton & Garam could have done a better job at some part (true to some degrees) and it's kinda upsetting for Compton (vs the other chapter when he wept a little & complimented Compton abt that how Rachmanioff should be played). So for the 2nd performance in Nagoya, he went mental at the orchestra I.e telling, throwing things to make it perfect during rehearsal while the professor was busy planning for his date (museum, sightseeing, hot spring bath etc in Nagoya) and didn't bother to show up to the concert to hear "his better attempt" at all. So yeah, Compton spiraled even worse than before and he went to Garam room again, to seek solace and obviously my lil baby already travelled to the hot spring with his husband.Compton then went to the reception to check and the hotel staff said he has checked out already. Graham was lying his ass off on the phone w Compton and told him he slept already (mid night btw). The 3rd leg of the tour is in Taipei and again, he made up some excuses to stay behind so that Compton/his orchestra can fly in advance so they can finally have some peaceful date. Oh well, wrong because Compton ass stayed behind and stalked Garam and caught both of their ass keke giggling in the museum date and the rest you already knew.

Could someone spoil how Compton eventually figures out that Garam and Heejae are together? And does Compton’s orchestra group fall apart or not? I don’t know, I kind of feel bad for Compton too.
