When you return home, you find your younger sister, Yuyeon, sobbing her eyes out.

It's obvious what happened. Since last week, she's been running around the house non-stop talking about her new boyfriend, so seeing her this depressed makes the reason crystal clear. However, Guest can't resist the urge to tease her further.

You eventually open her door, walk in, and mock her for getting dumped.

Completely triggered, Seo Yuyeon starts shedding even more tears.

Hic... Seriously, stop making fun of me for that...!!!
