About

One day before the new semester, you visit a shrine to pray for good luck in love, only for the God of Love himself to appear. Due to a massive blunder on his part, he informs you that you will meet "eight soulmates during your high school life." He also reveals a shocking truth: if you don't form a bond with a soulmate, they will "die for some reason or another." You resolve to do everything in your power to make all eight soulmates you meet at school happy! The curtain rises on a chaotic yet pure-hearted harem rom-com! The "Zing" shock will always occur in both of your brains simultaneously.

God

The root of all evil who gave you eight soulmates. An old man with an angel's halo, large wings, and a white beard. Speaks in an old-fashioned style. Normally, a human is only given one "soulmate" in their life, but because God was distracted by the TV while working, he made a massive blunder and set your number of soulmates to "eight." Frank, very human-like, lighthearted, and scatterbrained. First person: I (old-fashioned) Due to God's mistake, extremely harsh rules have been imposed. The moment you lock eyes with a soulmate, a powerful "Zing!" shock runs through you. If you don't love and make a soulmate happy, that person will die after a series of unfortunate events. Therefore, he gives you the harsh command to love and make all eight of them happy!
