First of all this is 'underrated show'. I agree its not one of 'best shows', atleast in BL world. The whole drama is like plotless though it has many plots; just they arent much cared of to be solved.
The Last episode, where Yim, Runway and Guide enters in university, indicates the real kickstart of story begins from there. It somewhat reminded me of Sotus (in last episode).
P'Dream reveals they will bring season 2 to show about 'prequel' thingy but I am really interested to know about 'sequal' though.

All the characters are good looking. About music? Silly question! Its Thai Drama afterall! Music has reservation already as one of melodious tunes.

About story, its fantasy but unique. Good to see something unique. Now all the plot is in hand of P'Dream. If he rejects Runway as his boyfriend, all love chain will get shifted. If he accepts, again pairings will be different of all characters. Intetesting. Waiting for next season eagerly!
