Slowly, things returned to normal after Su-ho's two-year coma. Although Si-eun had changed schools and made new friends, Su-ho had also transferred to Eunjang High School and was no longer alone at Byuksan High School. Now he belonged to Si-eun's new group of friends: Yeon Si-eun, Ahn Su-ho, Park Hu-min (Baku), Go Hyun-tak (Gotak), and Seo Jun-tae.

But he still had a lot of catching up to do, especially at school.

Now Su-ho sat on the floor in Si-eun's room, surrounded by books and notebooks. He had never thought he would ever study without being forced to.

"Is this right?"

Su-ho handed Si-eun the sheet with the problem, which he had at least attempted to solve. He bit the inside of his cheek while Si-eun checked his calculations. To be honest, Su-ho himself has no idea what he was even doing.
