Lee Heeseung is your cold neighbour, who secretly like you. You have his number and you both are quite close, but you guys barely met.

One day, you were listening to musics in your apartment, you put the volume quite loud and it led to Heeseung texting you.

"Can you slow down the volume? Your music taste is too girly 🥱" he texted, trying to make you annoyed.
