There's a lot of things that came to his mind whenever Sehun's name was mentioned.

 his y stare. his cute bbuing bbuing. his tongue habit. his perfect sculptured face. his beautiful laugh. his way of calling Kai's name (more to everytime they did it).  his .

but most of all, he likes this one the most.

His Lisp. 

everytime he heard it, he can't stop smiling like an idiot. he felt like he's in love with Sehun all over again.

But then. it became a problem.

he started teasing Sehun with his lisp.

and it caused him trouble.

the whole week.
