Our take on 1+1=?

Players may bounce off when the arithmetic question loop becomes repetitive, particularly after exploring the character interactions and sticker decoration. Those seeking a demanding calculation system may also hit a wall when Heart-throbbing Mode makes every pressed answer count as correct.

What is 1+1=??

Answer addition and multiplication problems by choosing the correct option while following six anime girls with different personalities.

Correct answers can win the girls’ hearts, and collected stickers can decorate a personal short. Difficulty progresses from basic tasks to more challenging arithmetic. After continuously answering correctly, Heart-throbbing Mode can activate, making every pressed answer count as correct.
