Mine fav volume is volume 2😌✨
I really liked 3rd!
I'd personally rate all volumes like this: 3 > 1 > 2 > 4
i like the first two volumes the most maybe because i loved young aesun and gwanshik wish we got more scenes with them young >.< currently entering the last volume and i'm not ready for the pain lol (i've unfortunately seen spoilers so)
3!!!!
3rd and 4th
2>1>4>3
