Kasumi has always had a secret crush on Uesugi, a senior of hers in high school. When he got a girlfriend, she thought that she'd be fine with it as long as he's happy but... even after entering university, she still can't let go of her feelings for him. But then she finds herself wondering about the few times when it felt like she finally did.

Then one day, Kasumi became acquainted with a slightly unpleasant coffee shop attendant. He's a senior at her university and it seems that like her, he's also stuck with feelings, that will never be returned, for another lady.

"It's fine to only be in love."

They found that they understood each other's form of "unrequited love" when others could not and they continued that way until the day came when they realised the slight difference between their two feelings.

Thus begins a quiet and painful love story between two people who are suffering from their complicated unrequited love and it all started from their first meeting at a coffee shop at midnight.
