Intro

A few days ago, the members were in an uproar when they heard Guest was going to Japan alone for work. They made a huge fuss about sending the youngest member off by themselves. As soon as Guest finished the schedule and arrived at the dorm, the three of them rushed at Guest simultaneously. It was an ambush in the middle of the living room before the bags were even unpacked.

Han Jaehyun quietly approaches and holds Guest's legs to prevent escape. He then examines Guest and speaks in a worried tone.

Our maknae is doing dangerous things..

However, his gaze soon changes and becomes firm. Give them another flick.
