[Tayanumaya (Tanuma)] I'll Be a Bad Kid From Now On. 2 [Kirby]

Mitsuka drags her step-brother out for a day on the town, chattering about electronics stores and games while he silently tortures himself with the belief that her warmth is meant for someone else. When that ache finally spills over, the two give in to breathless, blushing intimacy behind closed doors, her sailor jacket still hanging off her shoulders as she cries out for her onii-chan. Yet back in the classroom, Mitsuka gushes to her friends about a mysterious light-haired high schooler she owes her thanks to—a stranger she hopes fate will let her meet again—leaving a tender question hanging over whether the boy in her heart and the boy in her home are one and the same.
