Let's go... slowly / Loves... and non-loves

Grandpa Libero, attracted to piano teacher Maritè, takes some piano lessons from her, and Alberto and his friends start smoking against Lele's wishes. Laura, a colleague at the local health authority, is having problems with her ex-husband, and so Lele decides to help her, pretending to be her boyfriend. But it seems only Lele is pretending: Laura seems to have genuine feelings for the doctor.
