Help finding movie title

Hello,

Looking for a korean movie that came out in 2 parts, unrelated to each other, that was released around 8-12 years ago.

1st part - Man finds a game controller in trash, activates a girl who he falls for, in the end, she ends up with some other guy.

2nd part - Married dance teacher falls for her students boyfriend(tattoo artist), eventually getting a pink flower tattoo on her back after reprimanding her own student for it in the past.

Thank you
