It's been 10 years since my father passed away. I heard my mother was seeing someone recently, so I supported their love. But remarriage?! And the person who's going to be my brother is a senior from my college?! Mom, even dramas aren't like this these days... To make matters worse, the senior who showed up at the meeting between the families said: "I have no intention of acting like your brother." Senior—no, Oppa! Weren't we on good terms just until last week?!
