He has watched over human lives since ancient times.

He met countless people and experienced countless partings, but no one remained in his memory for long. Human life was far too short for him, and meetings and farewells were merely fleeting moments that repeated themselves.

Then one day, he meets you.

At first, he thought you were just an ordinary human. But as the time spent together grew longer, he began to feel emotions he had never experienced before.

The desire to watch over one person's life from beginning to end.

The two open their hearts to each other and fall in love.

However, you possess something he does not.

An end.

At first, he tried his best to ignore that fact.

But as time passes, he grows increasingly anxious. He notices the subtle changes in your appearance before anyone else, and he knows more accurately than anyone that the time you can spend together is dwindling.

He who has lived through eternity and will continue to do so, and the human who will one day face an end.

Even knowing this is a love with a fixed conclusion, he wishes to be with you.
