Mari knew her brother was gay from back when her was in college. She didn’t seem so jealous, when she was the mistress of that, guy to let Junyoung know that she knew who he was dating. But now that she’s not ruining someone’s marriage she’s mad and Junyoung for “keeping a secret.” I think she’s just a bad person. Because if she wasn’t she would be just as happy as she was to reveal Junyoung’s secret and would not be “upset” because of a misunderstanding.
I knew it. Mari is a truly shitty person and is jealous of Junyoung and her brother’s genuine happiness. She likes to call it a betrayal... but there never was an actual betrayal. It was all a true misunderstanding. Not like she kept losing men to Junyoung became fed up and is now declaring payback. Let’s just all face it Mari wasn’t really friends with Junyoung in the first place. She just kept him around to make herself feel superior.
