Maybe it was the curse of the black lilies that bloomed early in the winter - A girl falls in love with a girl before graduation. Her pure feelings are torn apart by a "tragic loop". You will weave her feelings by interrupting choices and typing letters.

It may have been the curse of the black lilies that bloomed early in the winter--.

It has been 18 years since the new and threatening virus "CLII," which killed more than 50% of minors, was completely contained.

People have completely regained their normal lives, but it has left a huge mark and problem in the society....

Hana Sasamori is a third-year student at Naeshiro High School in Sapporo.

She is a quiet girl, but inside she is always in a hurry.

With only a few days left until graduation, Hana finds herself repeating the same day over and over again.

Yes, that's right. I like you ......."

Hana strongly wishes for the happiness of "Jyu-chan" who saved her in the past.

Hana thinks, "I'm sure this feeling will make Trees happy.

I'm sure this feeling won't make you happy. ......

I thought I would put a lid on it and end it with "adolescent whimsy," as something I shouldn't admit.

However, that realization led to a deep, deep "curse"....

This is a story of love that weaves between two people in order to persist through such "love" and "curse".
