Our Dating Story: The Experienced You and the Inexperienced Me

When Ryuto boldly announces in class that he is Runa's current boyfriend, Maria bolts from the room. Ryuto follows and asks her if she is responsible for the nasty rumors about Runa. Maria's answer reveals a shocking connection between the two girls.

Runa invites Ryuto to the beach to celebrate their one-month anniversary in the sun. When nervous Ryuto is just starting to relax with his radiant, bikini-clad girlfriend, a typhoon strands the two and forces them to spend the night together in an inn.

The person who called Ryuto to the gym at night was actually Maria. She confesses her desperation to become Ryuto's first, even if that means dressing and acting like Runa. Ryuto is shocked. As the two talk it out, someone else watches from the shadows.

Ryuto adjusts to living in Runa's great-grandmother's house as the couple prepares for the upcoming summer festival. As the two work in the same shop during the day and sleep under the same roof at night, they start to imagine a possible future together.

As school begins again, Ryuto and Runa invite their friends to play survival games. They discuss the approach of their three-month anniversary.

Runa volunteers for the culture festival pamphlet committee and invites Ryuto to join to advance "The Friendship Project" with Maria. While Runa and Maria disagree over design, Maria and Ryuto get carried away talking about their favorite streamers.

Things have been tense between Ryuto and Runa since the culture festival. Ryuto plans to tell Maria they can't be friends anymore, but a shocking incident leads to a discovery that changes everything for Maria, Runa, and Ryuto.

With her relationship with Maria repaired, Runa dreams of her family living together again. She sets up a surprise dinner for her parents on Christmas Eve that, sadly, does not go as planned. Depressed, Runa asks Ryuto to stay overnight and comfort her.
