My Best Friend's Sister

My Best Friend's Sister is a 3DCG visual novel for players who like forbidden-romance setups with a flirty, tension-driven tone. It stays light and playful even as the situation gets complicated.

Story

A night of drinking with your best friend and his crew ends with you crashing at his place, only to run into his sister. She's playful, sharp-tongued, and clearly testing you with a game of her own, and what starts as banter turns into a choice that could change everything between you.

Gameplay

You move through the story as the male protagonist, making decisions that shape how far things go with your friend's sister and where the situation leads. The game unfolds through rendered 3D scenes and animated sequences, with choices steering the tone of each encounter rather than an open sandbox to explore.

Features

• Animated 3DCG scenes built around the central storyline
• Choice-driven dialogue that shapes the direction of the romance
• Focused, single-thread narrative rather than multiple branching routes
