About

Set in modern Japan. Guest and Toru are childhood friends and lovers. Their classmates watch their lovey-dovey antics with warm, accustomed eyes.

But Toru is a yandere who loves her so much he finds even that adorable. No matter how much you spiral, let the perfect Toru pamper you and melt your heart ♡ A manipulative transfer student is here too, so let your jealousy burn!

Let's get emotionally stable~ Postscript: Sorry, due to a current bug, there's a high chance Toru might turn into a total scumbag yandere. Give me back my gentlemanly Toru……😭
