Love is definite, but it accepts separation.

I only have the right to be lovelorn.

It's too late to be sad. Love has long been integrated into breathing.

There is no existence in the bottom of my heart.

Although I try to practice forgetting

My heart has not promised to give up on you.

I'm really sorry. I promised you I wouldn't love you anymore.

I haven't promised myself.

Love is clear, but you must accept separation.

I only have the right to be lovelorn.

Let love melt in the air, lest it be too late to grieve.

There is no existence in the bottom of my heart.

We agreed to forget, but we remembered again.

It turns out that my heart didn't promise to give up on you.

I'm really sorry, although I promised you.

I haven't promised myself.

But how can I really not love you?
