@IdleBones i think ho seon is in love with yi gyung which is why he got so worked up in that argument (since she's with bong won). i dont think he fully trusts that new person after they suggested just turning yi gyung into a vampire
watched the show years ago and just binged all the content from the manga, the FEELS
i def recommend reading this if you watched it when you were younger, you'll appreciate it 2x as much : .)
