Thank you for the list. I need to check out if Spotify has the sound track because the songs are in my vibe house this winter.

I agree the music is amazing! I could make a playlist with the sound tracks and post them on a different discussion

the last IG, didn't he already participated in S2?

You mean he'll participate in another season? Like The Boyfriend? (sorry that was a spoiler)
