Hello @bettyhandayani,
Unrequited love. Poems, books, songs have been written about it. The challenge in loving someone is often getting that person to love us back. It is so hard to let go of love when it is not shared. It hurts. That's what you capture here, the longing. Love is not rational, and it is not rational to hold on when there is no hope.

However, was it not Shakespeare wrote said,

Love is not love
Which alters when it alteration finds,
Or bends with the remover to remove

We love with our hearts, not our heads. You do a good job of making us feel that.

As for the pronoun confusion: translators notoriously mix up pronouns. In this case, pronouns figure largely in the story and that is what @zeraton refers to in his comment. While the confusion is distracting, it is not insurmountable. You might want to go back after you have run a story through a translating program and check to see that the program has not mangled the pronouns :)

Thank you for sharing this story with us and for engaging with other authors in the community.
