Ahhh, Vill looks gorgeous in the BTS for this new MV.
From the BTS, this song is about how Vill doesn't treat her boyfriend too well like she neglects him and stuff but she really loves him but doesn't take the chance to appreciate him and tell him her feelings, so in the end they break up and he marries someone else. It's a very sad song. Vill had to do many crying scenes. Awes, Vill is sooo gorgeous, can't wait to see it. Ahem, Vill, Son. Hahahah.
