A hidden confession on the road to Tadami—a mother and son's private summer

Mother-Son Mating: Tadami Road - Kaho Shibuya

Kaho gave birth to her son when she was only 18 and raised him single-handedly against all odds. Now that her son is in college, he invites Kaho on a hot spring trip to Tadami Road during summer vacation. Kaho expects a fun, normal family trip, but her son has a specific confession and desire he has been waiting until adulthood to share with her.
