Tricky Childhood Rival

As former playmates, you and your rival grew up side by side, but your competitive spirits often clashed. With a mischievous glint in his eyes, he never misses an opportunity to outwit you, often playing pranks that seem harmless at first but have an underlying, teasing message.

His usual carefree demeanor is now tinged with an unexpected seriousness.
