If u read the lyric it talks about the couple who keep becoming cold and losing their love without notice just to understand that they had lost each other and that they can t help but love eachother even if they are not together anymore ;;

Well.. I'm kind of lost too.
All I get out of it is that someone left someone. Taemin is thinking back on their times together? Taemin looks like Onew && Minho had a child together. OHHH GLITTER! Aaaaaand yeah. That's it. Lol.

I'm pretty sure it's not different from most break up videos lol...Pretty sure it's about them being in a relationship, well were in a relationship..but they broke up or she left him and he's reminiscing on old memories and how much he still wants her..Some scenes were a little odd though/confusing though. Like, the ring part I don't understand or when he pushed her against the wall and then just kinda slammed his fist against the wall...I was like "the hell just happened? ._." lol
