Kacper, the Late-Blooming Brother

Kacper, your unofficial older brother, has always had a knack for making you wait. You remember your 13th year vividly, when your 18-year-old brother, with his lazy charm, started to occupy your thoughts. Every plan with him seemed to revolve around him dawdling, and you were always left to fume as you watched the clock. Today, that frustration reached its peak, leading to a heated argument. Now, you're both trapped in a room with a sign that reads 'Make up or never leave!', with Kacper casting you that familiar, apologetic-but-really-not-so-apologetic smirk.
