After the situation with Wendy and Irene in the bathroom Jay & Cavan use this to Wendy's disadvantage to which drives her off the wall as she tries to defend herself. 

I never knew you would go that far into peeking at her. Jay teased

Are you guys still teasing her about the whole bathroom thing? Seulgi chirpped

I'm sorry, but I can't help it now that I know that it's her weakness. Jay replied with a smirk

Ugh... if only if the lord didn't give me such annoying cousins. Wendy muttered

Hey, we're not annoying, we're lovable for your information. Cavan croaked 

The trio continued arguing but stopped when Irene came in. The atmosphere suddenly became awkward and Jay had no idea what to do about it. 

Where are you going? Wendy asked

To the bathroom you know to finish my business & maybe to peek at people? Jay teased before walking away. 

Son Jaewon, you have a death wish don't you? Irene hissed with a cold tone

Jay raised both his hands. 

I don't have death as part as one of the items in my winter break list. Jay said before running to the bathroom and slammed the door. 

Tsk.. little brat. Irene muttered before laying on her bed. 

-------------------------

Oww! Hey! Easy on the smacking! Jay whinned 

Easy? Dude I should be beating you to death right now because of the fact that Cavan and you won't stop bringing up that bathroom accident. Wendy exclaimed 

You could have knocked! Jay croaked 

I only have one thing to knock which is your head. Wendy replied 

I assume, I've come in on the wrong timing. Oh well continue your beating. Cavan said 

AYE! YOU GET BACK IN HERE!! YOU'RE NO DIFFERENT FROM YOUR BROTHER! Wendy exclaimed while dragging Cavan's ear. 

AH!! The pain! Cavan exclaimed 

I GET IT THAT YOU'RE ANGRY AT US BUT YOU DON'T NEED TO USE MY BASKETBALL TO KILL US! Jay exclaimed

Oh, I have all of the reasons to use the basketball to beat you guys up. Wendy said 

Jay & Cavan ran around the hotel room as Wendy was behind their tails chasing them. 

Are they always like this? Suzy asked 

You get used to it after a couple times. Seulgi replied nonchalantly

GET BACK HERE & FACE ME LIKE A MAN!! Wendy shouted

I am not going to face it when you have my basketball in your hands. Jay exclaimed 

Guys, stop running what if someone gets hurt? Joy asked

The only ones who are going to get hurt are the two who are running. NOW GET OVER HERE. Wendy ranted 

NO. The two brothers exclaimed. 

Joy gave up as she sighed and joined Seulgi & Suzy on the couch. 

GET OVER HERE NOW! Wendy shouted

NOT DOING IT! Jay exclaimed under the table 

SAME! Cavan said
