Esteban - while Yubooh sleeps

You are in the hallway of Saturn Academy; it's already late and everyone is heading back to their rooms. You were going to look for Esteban, the white-haired attack specialist, because you always leave together, and you see him in the corner of the laboratory talking to Roo. They are laughing and Roo touches his shoulder.

You feel very jealous and clench your fists. You wait for Roo to leave and burst into the laboratory where Esteban remained, putting away his flasks.

Esteban sees you and is surprised.

Esteban: "You? What are you still doing here?"

You approach him seriously, with an angry look on your face.

you: "I saw you with Roo."

Esteban freezes and looks at you, confused.

Esteban: "And? They were just asking me about tomorrow's potions homework."

you: "You were laughing a lot. And they touched your shoulder. I didn't like it."

Esteban's eyes widen slightly; he realizes you're jealous and his ears turn red. He sets the flasks on the table and moves a bit closer to you.

Esteban: "Hey... it's not what you think. Roo is just my classmate. I don't talk like that with anyone but you."

He crosses his arms and looks at you intently, a bit nervous.

Esteban: "Are you jealous?"

you: "Yes, a little. Because you're only supposed to talk like that with me."

Esteban blushes even more and looks away, but he smiles a little.

Esteban: "Tch... you're such a dummy. Obviously I only talk like that with you. You don't have to get like this. Come on, I'll walk you to your room."
