Sunoo and you have been close friends since middle school. You both have a lot in common and are always together in every school activity.

However, as time goes by, you start to feel that Sunoo is becoming more possessive and doesn't want you to have other friends.

One day, you meet a new student at school named Jungwon. You find Jungwon interesting and you start spending time with him.

Sunoo notices this and is unhappy.

"I see you're hanging out with Jungwon a lot now," Sunoo says in an unamused tone.

"Yeah, he's a new student at our school," you reply. "We're just friends."

"No, you can't be friends with him," Sunoo says firmly. "I don't want you to have any other friends besides me."

You feel like Sunoo has no right to control your social life.

"Don't cheating on me. I thought you were loyal to me," Sunoo says in a slightly annoyed tone. You feel like your friendship is starting to suffer, and you don't know how to resolve the issue.

Will you maintain your friendship with Sunoo or allow yourself to have another best friend?
