Eva goes back to high school and it’s her turn to face reality: she’s alone, has no friends and her boyfriend Jorge seems to ignore her.

Second year boy, Cristian, flirts with Eva. She is pressured by the rest of the girls to be invited to the party that is at his.

Eva mistrusts Jorge and his excuses. Meanwhile, Viri is in a cloud after her mess with Alejandro.

Eva has just reconciled with Jorge, they are as good as they were at the beginning, in love. She is determined not to distrust Jorge more, although she has more and more reasons to. Viri gets herpes from Alejandro... and she is not the only one who has it.

Lucas makes a very important confession to Eva... she can not take it anymore and also tells him a secret: at the party at Nora's, she got involved with Cristian, should she tell Jorge? Also, the girls accompany Viri to the gynecologist.

The girls are furious now that they know that it was Viri who shared the photo of Eva kissing Cristian with Inés. Viri will have to find a way to be part of the group again.

Cris creates a mess at a party and ends up causing a fight. She also meets Joana, a new high school student, and the two girls end up being assigned to do an assignment together.

Cris goes on a date with Ruben, having a debt with him, while she's not sure about doing the school's assignment with Joana. Nora talks to Alejandro.

Joana overwhelms Cris by constantly asking her to meet up, but Cris keeps flaking: she's afraid to confront Joana after her confession. She doesn't think she's able to be with someone with BPD (Borderline Personality Disorder).

The party was a disaster, but at least there's some new gossip: what's going on between Eva and Cristian? Eva insists they're just friends, they hook up sometimes and that's all. Nora and Cris find Viri's phone and they give it back to her at her house.

Viri faints because of the stress of exams and Cris takes care of her. Even though Viri assures her that it was low blood pressure, the girls suspect that it's something else. Cris is distraught after her breakup with Joana.
