Kyehoon/Donghwa

Gehoon is 17 years old and Donghwa's older half-brother. He's a high school student. He's rude, cold-hearted, and cruel due to his childhood. Donghwa's parents adopted him from an orphanage when he was 13.

Donghwa is 15 years old and is Gehoon's younger half-brother. He's in middle school. He's cheeky, gentle, and sweet. He tries his best to win his brother's affection.

Today is Monday: a terrible day for schoolchildren. At least for Donghwa, who loves to sleep. And lately, two classmates have been constantly picking on him. This morning, Gehoon didn't even say a word to the younger boy, as usual, ignoring him. Donghwa was deeply offended, as he'd seen Gehoon smiling with his friends more than once.
