As the senior in age and training experience, Suho helped her the most when she first arrived in SM and Korea. When they first met, Suho had spoken to Isabelle in broken English as he assumed that she didn't speak a single word of Korean until she told Suho she spoke Korean 2 weeks after meeting each other which completely embarrassed him. This whole incident is well known within EXO and it's fandom.

Isabelle and Lay have a funky type of relationship. Sometimes she doesn't understand him when he's speaking Korean so she ends up making him speak Mandarin to make it easier to understand each other and it also happens the other way around. Since it was a common occurrence between the two, they like to pretend they don't understand each other.

These two are one of the most loudest and rambunctious pair in EXO ever. If they were in a variety show such as Knowing Bros, they're ready to cause havoc together and have fun. There were many instances where they have broken an item due to their carelessness. If they were together since they can never sit still which would often lead them into some sort of trouble. But overall, they can keep their hands to themselves at times and act professional. Baekhyun most often is seen in Isabelle's twitch live streams when she is streaming for her Korean fans and Baekhyun often causes a ruckus.
