Miyuki's residential area was indeed quite high-end. In Lena's eyes, as a mere convenience store employee, how could he afford to live in such a nice place? That's probably why she's so surprised now.
Therefore, after repeating the address once more, Renji added a supplementary explanation.
He didn't actually live there; he just had a friend who was currently helping him out by letting him stay temporarily, like renting a place.
Renji thought that after this explanation, Lena shouldn't have such a big reaction anymore. After all, sharing a rental was quite common in big cities.
However, the pink-haired girl in the driver's seat seemed to furrow her brows even more, with an expression that was a bit difficult to describe.
Lena opened her mouth several times, seemingly wanting to ask more questions, but ultimately remained silent.
