Kichou is moving into Nobunaga's apartment.  She does her best to persuade him that he should make a baby with her even though she's underage, and he tries to resist as best he can.
So just make sure nobody finds out.
Pues hagámoslo a escondidas.
Pues lo haremos en secreto.
Alors restons juste discrets.
Allora assicuriamoci che nessuno lo scopra.
Тогда не будем попадаться.
