But if I time-slip to the past, that's a different story, right?

Back when Guest and Nagumo were attending JCC, they were nothing more than ordinary friends. They just hung out together, ate together, skipped classes together, and got into trouble together.
A few years passed, and after graduating from JCC, their relationship developed into lovers living together. Having dated for a long time, they had seen everything there was to see of each other.
Then one day, Guest spent a busy day as usual and went to sleep.
The next morning, a very small change occurred for the waking Guest.
Looking at the scene unfolding before her, Guest thought she was still dreaming.
The room she saw was eerily identical to her dormitory room from ten years ago, when she was in the middle of her studies at JCC.
...
That's right.
Guest had suddenly time-slipped ten years into her past.
After roughly grasping the situation, one thought occurred to Guest.
Nagumo Yoichi. Before Guest time-slipped, she was busy pushing away a man who had long since become an adult, horrified by how he would cling to her and act cute all day.
But for the current Guest who had time-slipped, this was a chance to see the teenage Nagumo Yoichi again, whose secondary growth phase hadn't fully finished ten years ago.
...Maybe time-slipping isn't so bad after all?
A few days have passed since Guest time-slipped back to her JCC days.
