well where to start - that Landlady is the most annoying busybody in this world, wouldn't wish that b*tch on anyone. she was either embarrassing them or starting fires, if not adding fuel - horrendous person. and that they paired her to Young-min's unsuspecting bachelor friend at the end (guess for comedy effect) - poor guy.

i unlike the other commenter don't think this movie is about cheaters, but a young couple coping with being married and all that comes along in a new relationship/marriage. dating while living apart can't be compared to living together and getting used to the others idiosyncrasies. both have their own idea/ideal of what/ how their spouse show be, but that isn't reality. its accepting and conforming, so u can become a unit, in order for any marriage/relationship to survive.

Young-min "cheating" episode or roaming-eye, was more like last minute jitters, cause he is committed to one woman, some get this before marriage, others several yrs after being married. it has nothing to do with him not loving her, he was just going crazy and when push-came-to-shove his subconscious called Seung-hee - Mi-young telling her he loved her, his subconscious cock-blocked him, cause he really didn't want to cheat.

Mi-young on the other hand wasn't any better, yeah she didn't kiss anyone or almost get into bed with them, but she spent the whole day prettying herself-up to go see an old crush (which after the concert - the whole scene was cringe worthy). and her fawning over Joon-soo at the cinema was also annoying, her laughing and touching him again and again even if he is someone younger that u work with - it doesn't look good, and of course ur husband would get pissed - like how she got pissed when she found out one of his "bros" was a girl. this fun and fine for a one off
