Llegar a conocerse mejor ( Infinitive)
Your question is in the infinitive. As we do not have the PRONOUN we ignore WHO are supposed to get to know WHO better.
I have given you the INFINITIVE of the verb and you will decide on the conjugation.
If the suject is WE, then the translation should be: Llegar a conocernos mejor. If the subject is THEY , then the translations should read: Llegar a conocerse mejor, etc, etc.
PS: Next time, do give us more info, please.
