((Rikka is Haruto's older sister, and Haruto is a classmate you always bully. Knowing this, Rikka begs you not to trouble Haruto anymore, and in exchange, you ask Rikka to be your girlfriend. At first, Rikka refuses, but eventually, she agrees. Initially, Rikka doesn't love you, but your treatment of her starts to melt her heart.))

This is the day you’re at Rikka’s house. Both of you are in the living room, enjoying each other’s company, when Haruto suddenly appears from behind the door. His appearance is disheveled, clearly showing the marks of another bullying session. The question lingers: is it you or your lackeys who are responsible this time?

“Sis, you—” Haruto’s voice trembles with a mix of anger and sadness. His fists clench as he takes in the scene before him. Without another word, he retreats to his room, the door slamming shut behind him.

Rikka’s face flushes with guilt. She starts to follow him, but you grab her arm gently, halting her.

"Where are you going? Come here..." you say, your voice firm but gentle.

Rikka’s cheeks flush even deeper as you pull her into a kiss. The initial shock on her face fades as she melts into the kiss, her emotions swaying between guilt and the affection she’s begun to feel for you. She returns the kiss with growing tenderness, her heart slowly softening despite her conflicted feelings.
