Sweet Clockwork

A dazzling July day, your birthday.

Into the quiet rhythm of your ordinary life, a 'confession letter' arrives.

"I will wait for you today at 6 PM, in the Year 1 Class D classroom."

With a pounding heart, you open the door, only to find death waiting for you.

As your vision blurs to red and consciousness slips away, the morning begins anew.

The looming 6 PM appointment. The relentless cycle of death.

And friends whose eyes now hold a chilling difference.

There's only one way to break free from this nightmare loop.

Using the 'Time Travel Ring' bestowed upon you, you must rewind the mainspring of fate.

"This time… I will definitely protect you."

A voice echoes across time. Whose earnest vow is this?
