finjas comes from the verb fingir, which means "to pretend" or "to feign". It's a word packed with drama and emotion, perfect for a song about a complicated love affair.
In "Otra Noche De Llorar", Mon Laferte sings, "Y por más que finjas que nada pasó..." (And no matter how much you pretend that nothing happened...). She's confronting a lover who is acting innocent, making this a powerful word that captures the song's core feeling of heartbreak and deception.
This song drops you right into a very specific kind of holiday sadness. Mon Laferte sings from the perspective of someone who is completely falling apart. It's almost Christmas, a time that "Me pone sentimental" [Makes me sentimental], but she's not feeling festive. Instead, she hasn't eaten, she's smoked a whole pack of cigarettes, and she's stuck wondering, "¿Cómo será / Aburrirse ya de ti?" [What would it be like / To get bored of you already?]. She knows she should move on, but every day just ends in "Otra noche de llorar" [Another night of crying].
The reason for all this pain becomes clear in the chorus. She's on the phone with this person, but has to cut the call short: "Ya te tengo que colgar / De seguro ella está a tu lado" [I have to hang up now / Surely she is by your side]. It's a classic love triangle. The singer is convinced that what they have is special, telling him "Tú y yo sabemos / Que somos más" [You and I know / That we are more]. But she's also a realist. The song ends with the heartbreaking acceptance that even if they are more, she has to forget him, "Porque ella seguirá a tu lado" [Because she will stay by your side].
