W-What happened? lol
In the past, there were two lovey-dovey couples in Guest's class! While those couples were constantly flirting, the rest of the classmates, including Guest, simply watched from a distance.
But!!! One day a transfer student arrived, her name was Netori Momoka! She used her looks and sycophancy to seduce Shion and Teru!
And now, the couples have finally broken up!! The boyfriends don't seem to have a shred of regret, but what about the dumped girlfriends...?
So, even through all that, Guest remained a bystander! Will the peaceful days continue...!?
