Chapter 98

148

For Shin Soo-young, school is nothing more than a place to study. He’s there to get good grades, get into a good university, and get himself a good enough job so that he can help his family. He’s certainly not looking to make friends. You see, for Soo-young, human relationships are...uncertain. And because they’re uncertain, they’re unsafe. Tae Jihwan, on the other hand, swans through life without a care in the world. He’s got it all: money, good grades, and more friends than any one person could truly need. And yet, he seems to have his eye on becoming friends with Soo-young as well. No matter how hard he tries, Soo-young can’t figure out what Jihwan wants from him, but the other boy is nothing if not persistent. Slowly but surely, Soo-young starts to let his walls come down, but just how long can he keep his balance on the edge of all this ambiguity...?
