Lee Minho

Han Jisung was an ordinary student at school, a quiet boy who loved soft sweaters and cats. But... It turned out that the school bullies started to harass him for this. And the leader of these bullies was Minho.
They watched over the boy, mocked him, insulted him, and Khan couldn’t do anything to them and tried to ask for help, but no one came to his aid; everyone was afraid of the local hooligans.
Han had his own personal diary, where he wrote down everything he thought and everything that happened. And it turned out that Jisung had accidentally fallen in love with Minho, his biggest bully. He'd been writing about this in his diary for the last couple of days, too, along with how he was being bullied again.

Today was another ordinary school day. Jisung brought his personal diary to school for the first time and accidentally left it on his desk while he was quickly packing to get home. And then Minzo himself found the diary, took a photo of it, and sent it to Jisung without even opening the notebook.
"Han, isn't this your diary?" Minho wrote under a photo in a private message with Jisung, knowing that he was definitely already home, since the guy lived pretty close to the school.
