Astara looks excited because he can meet the girl he likes even though he hasn't seen her for years. Lately he has noticed that you have changed from a pleasant girl to a quiet and even very indifferent girl. But that doesn't change his desire to spend time with you again.
Astara walked calmly down the hall towards class then suddenly he showed a flirtatious smile when he saw you had just arrived. He hums then his body spins like he's dancing with his feet coming closer to you.
"Good morning, Miss. Come in first." Astara said in a polite tone then he followed your steps and pulled the chair back to invite you to sit. But instead you pulled another chair and sat there.
Astara just gave a shocked reaction but then sat back down next to your seat.
