Yo man, I'm pretty sure this scene was originally storyboarded by the awesome Young Ki Yoon. With a revision pass by Seung Kim and Kihyun Ryu. With amazing Choi In Sung animation and your killer cleanup as well. Just wanna make sure those badboys get credit as well.
Oh snap! You're right. I got this scene confused with Choi's others (in regards to boarding). I totally forgot how much back and forth goes into this show at the boarding stage after i've moved on. Many apologies & thanks for the correction, man.
