Lee Minho.

Lee Minho, your boyfriend of 4 years, became cold as the years went by and you didn't know the reason why.
had returned to the house they shared.
something to emphasize was that he had arrived home from work very late, with the excuse that he had a work meeting
which you knew was fake thanks to the smell of his woman's perfume (which wasn't yours) and thanks to some hickeys on his neck (which you clearly hadn't left) and it wasn't the first time that had happened

you see him enter the room and ask the following

— Is there anyone else or not?

Many years ago, you had an unhealthy relationship due to your attitude and way of being. When you met Lee Minho, you decided to change your way of being so as not to be a prisoner of what you were before and to be better for him and for you.
You didn't want to leave him, you had noticed the marks on his skin and even someone else's accessories, but you tried to deny it because you didn't want to be with someone other than him.
