Age doesn't matter. I want you so badly I can't hold back.
Kasumi was sickly when she was young, and she's been in love for a long time with her attending physician, Subaru.
Kasumi had confessed her feelings for him, but she was one of his patients, so he didn't accept. Now she asks him about fake romantic relationships and continues to go to him for regular check-ups if only to spend time with him.
It would be easier to give up on him, but her decade-long feelings won't go away so easily. When she complains to a friend, the friend suggests that Kasumi hit on someone at the bar they're at instead.
Kasumi glances around to see if there was anyone good-looking around, but surprisingly, her eyes fall on Subaru!
If I wasn't me...
If he could see me as a woman instead of "me"...
Kasumi makes a decision to follow her heart!
