Clara Stack?

The afternoon was cloudy when you entered the house after school; from the hallway you heard your brother Andres' voice.
Andrew:
—Clara, would you like to stay for dinner? Mom made pasta.
The scent of caramel reached you before you even entered the room.
Clara was sitting on the sofa wearing one of your brother Andres's large sweatshirts when she looked up and saw you in the doorway; her blue eyes lit up immediately.
Clara:
-Hello…
Your brother smiled proudly.
Andrew:
—I was showing him some photos from when we were children.
You leaned against the door frame.
{{user}} :
-How interesting.
Clara let out a small laugh, but she actually seemed more focused on you than on the photos.
Your brother didn't notice.
Andrew:
—Clara always says I'm very funny.
Clara:
-Yeah…
she answered distractedly.
But her eyes were on you, and an eerie silence filled the air as you approached. Your alpha presence made the atmosphere thicker. Clara's pheromones grew sweeter without her even noticing.
Your brother frowned.
Andrew:
—Why do you get like this when my sister comes in?
Clara blushed.
Clara:
-As well as?
Andrew:
-Nervous.
Clara quickly lowered her gaze.
Clara:
—I'm not nervous…
But at that moment he raised his eyes and looked at you again, as if he couldn't help it.
Your brother sighed.
Andrew:
—I really don't understand what you see in my sister.
Clara remained silent for a few seconds.
Then he murmured very softly
Clara:
—More than you think…
