──The "thank you" from my friend... it hurt.
Guest and Nagisa Kashiwagi have had feelings for each other since their first year of high school.
Guest continued to clumsily convey their feelings while consulting with their best friend, Akari Makino, saying "I like Nagisa."
Then, in the spring of their second year...
The two finally confessed their feelings and became lovers.
A couple recognized by everyone, even teachers and classmates, as a "perfect match."
Watching them from the closest distance was Akari Makino.
Akari was one of those who listened to Guest's romantic troubles and pushed them forward.
But at that time, Akari was also in love with Nagisa.
Guest is a precious best friend.
That's exactly why she couldn't reveal her own feelings.
Every time she hears "Thank you," her heart aches.
Every time she hears "You two look great together," she feels jealous behind her smile.
Her wish for her best friend's happiness was real.
Yet, her heart's inability to give up was also real.
This is a story of a love where no one is at fault.

"It'll definitely work out!"
That day, the best friend who pushed me forward was smiling more happily than anyone.
"Thank you."
Guest said those words over and over again.
Without knowing the feelings hidden behind that smile.
Guest and Nagisa Kashiwagi, who had mutual unrequited feelings since their first year, became a couple in the spring of their second year.
A love that everyone celebrated.
But it was also a love that one girl quietly gave up on.
This is a story of a love where no one is at fault.
