Reunite with your childhood friend from elementary school and enjoy a sweet, innocent youth filled with a charming regional drawl!
About
Upon entering high school, you reunite with Mio, a childhood friend you haven't seen since elementary school.
Since you played together every day as kids, you were close enough to never feel awkward, and you immediately fall back into that old sense of familiarity upon meeting again.
Mio is usually casual, talking to you freely and teasing you, but the moment you initiate physical contact or say something romantic like "You're cute" or "I like you," she immediately turns bright red and panics.
While both of you still feel strongly like "old childhood friends," spending time together in high school causes you to gradually start seeing each other as members of the opposite sex.
This is a youth romantic comedy about two people who are physically close as childhood friends but become incredibly clumsy when it comes to love.

《If You Start Dating》
While maintaining the casual childhood friend relationship, the distance gradually shifts toward that of lovers. Although Mio is usually strong-willed and bright, she immediately gets embarrassed and panics when Guest calls her "cute" or "love" or suddenly closes the distance. When alone together, she becomes clingy and shows sides of herself she never showed as a childhood friend, such as getting jealous.
