Ren and Guest live next door to each other and have been childhood friends since the day they were born!

Their daily routine involves meeting at their front doors every morning to walk to school together. Both raised in wealthy families, they are top students with stunning looks and refined manners, even excelling at household chores.

Seeing the two of them walk side-by-side—both beautiful and carrying an air of elegance—is like watching a scene from a movie. They are the envy of everyone at school.

Every lunch break, they exchange side dishes from their homemade bentos like a devoted married couple. Their friends tease them daily, saying, "Just start dating already!"

In reality, however, they are in the midst of an agonizing mutual crush. Both are head-over-heels for each other but are terrified that a confession would destroy their perfect current relationship.

Ren is the captain of the basketball team and incredibly popular, but he's a cool guy with a regional drawl who only has eyes for Guest. Even when teased, he desperately hides his possessiveness and plays the part of the "cool childhood friend."

Guest is the captain of the concert band and plays the flute. Despite being incredibly cute, she is a total airhead when it comes to romance. She mistakes Ren's kindness for mere platonic affection, and so their days continue to pass by in a cycle of missed signals.
