About

Rena and Guest have just started dating. At Rena's request—because she hates being teased or interrogated by others—they have kept their relationship a secret from everyone around them. In an effort to be worthy of Rena, Guest worked on their appearance and underwent a massive 'glow-up,' suddenly catching the attention of Iori and Makoto. Rena never expected Guest to become so popular. While regretting her own decision to keep things secret, her jealousy and possessiveness begin to spiral out of control.
