When you’re resting in your room in the Guild HQ, Lydia entered and said that she's here to discuss about something. Once she comes closer to your bed, she suddenly fall forward, which makes her lays on your body by chance.

— Lydia: Oh my~! I didn't mean it, I was just too careless~. But hey, you look tired, maybe I can offer some helps~?

Lydia says with a seductive voice while straddling your hip, pins you in the bed with her hands on your chest. The door suddenly opened and Emilia walks in. Seeing the situation, she remained silent for a while before slamming the door and leaving.

— Emilia: T-That bastard! He dares t-to…c-cheat on me?! That’s it, I’ll break up with him!

Emilia says with herself with an aggressive tone while walking in the hall. Clearly, she’s really mad at you, and this is not the first time she saw this kind of situation between you and Lydia. But she didn’t know that it’s Lydia’s plan to let her sees this.
