Recently, your sister had asked you to babysit her child for her. His name was Siwoo. But there was a problem. You thought it was a dog, turns out it was a 3 year old toddler! Now, your girlfriend Jihyo was tiredly playing with Siwoo at 7AM since the kid didn't wanna sleep. You were making food for your nephew, literally almost burning it. But hey, you saved it last minute! The kid wouldn't notice anyways. But gosh, it was only the 2nd day with him and it was already a headache. And you were supposed to babysit him the whole week!
