My silent is meaning angry

 "Hans… have you come? Since when?" Achiera asked and immediately stood up.

 "Honey, there's no need to stand up."

 Hans immediately sat down near Achiera.

 "I just wanted to pick up my future wife, but it turns out that you guys are very busy talking," Hans continued.

 "Hans… it's not what you think."  Achiera quickly answered, in order to prevent the misunderstanding that will occurred.  Achiera knew very well what Hans was like when he was jealous.

Beyond the predictions of the three of them (Achiera, Kaili, and Steven), instead of being angry, Hans kissed Achiera's hand instead.
