your sunoo sunghoon would be always whipped when sunoo looked at him lovingly, he would stutter or avoid eye contact. Sunoo just always liked to look at him that way to see him flustered, even the members see how sunghoon reacts by that. If the members try looking at sunghoon lovingly, he wouldn't react at all. Today sunghoon, sunoo, heeseung and ni-ki had a mission together. As they talked about what to do, sunghoon looks at sunoo as he continued talking, which gave sunoo the opportunity to look at sunghoon lovingly. Sunoo looked at sunghoon and sunghoon started to get whipped by him

Sunghoon: y-yeah, t-thats what we s-should do...

he stuttered
