Why kangmoo got jealous of kirin's friend? Which episode is it?

I forgot which chapter but it's when kirin got drunk and kangmoo came to pick him up. He asked that guy why kirin is the only one who drunk? Everybody was afraid to kangmoo expression at that time. In the car kirin said those two are cute to kangmoo because they are tiny/short. That's why this time kangmoo deliberately mocking that shorty guy when he saw him again.

Tq, i found it. 62
