"I was able to overcome it because you were by my side." "I think I've been able to do well until now because you were next to me, senpai." Keiko and Ran. It's already been over a year since the two of them, a teacher and a student, have been sharing their daily lives together. The seasons have changed from winter to spring and summer. April Fool's Day, birthday parties, spring shopping, and baths. Even in the days of stretching together, the time for farewell is approaching... Just reading it gives a refreshing feeling as if your body is stretching out. Filled with practical and useful stretching know-how that you can actually try out, this is the final volume of the full-fledged 'stretching' drama.
