Reo's appeasement and Lisa's time with Alex

Reo didn't know what happened to Arya to make him refuse to answer his question, but when he heard Arya talked about Elena's instinct, he felt relieved.

Reo is a beginner in the relationship, so he doesn't know how to make his boyfriend feels more secure. 

"You are stupid," Reo said while taking a deep sigh.

Arya was stunned when Reo said that he is stupid. Before Arya could ask Reo why did he say that he is a fool, Reo already opened his mouth to answer Arya's question.

"Why are you so nervous like that? It is okay for my older sister to know about our relationship even though I never tell you anything, but I already have a plan to tell my sister about us.

I am sorry for making you feel insecure. I should tell you everything from the beginning, but I used to handle everything by my own initiative without telling anyone before," Reo answered honestly.
