Logan- I Don't Care" by 2NE1. I chose this song for him because it basically is saying "I don't care anymore, so don't come crawling back to me" and Logan's been on the back burner lately and he even said that he would say one last thing "and spare [everyone] his company" in the last episode, meaning he knows that he's kind of getting brushed off.

Patton- Aze Gag by Mamamoo. This song's title literally translates to "Dad joke" in Korean, so yeah, you BET that it will fit Patton. It's FULL of puns (in Korean, of course).

Roman- So Hot by the Wonder Girls. Come on! The chorus is basically the singer saying that she's "so hot"! And Roman would probably think that! A lot!

Virgil- Kill This Love by Blackpink. This song basically is about preventing heartbreak and some of the song's lyrics remind me of trust issues, and it would fit Virgil because the lyrics are about "killing" love before heartbreak.

Janus- Bad Boy by Red Velvet. The lyrics are about a girl trying to get a boy to "follow [her] like [he's] under a spell", which reminds me of manipulation. And Janus is Deceit, so... yeah.

Remus- Peek-A-Boo by Red Velvet. The music video depicts the girls playing a sadistic game with  and ultimately killing a pizza guy. Need I say more?
