Shortly after BTOB members wrapped up their "Missing You" promotions, Sungjae was packing his luggage to film for his upcoming new variety show "All the Butlers" along with Lee Seunggi, Yang Sehyung and Lee Sangyoon. In the variety show, they will spend a whole day, including overnight, with a "Master" at the master's house, living according to the master's schedule. Sungjae's room was a mess as he pulled everything out trying to decide what to pack. 

Sungjae: Hyung, help, what would I need? I don't know what to pack!!

Eunkwang: It's just one night, just a set of clothes to change into and that's all

Hyunsik: Won't you need to bring toiletries too? Toothbrush, shampoo and stuff

Changsub: Won't you just use your master's toiletries? You're supposed to live their life, you should just use whatever shampoo they use ㅋㅋㅋ

Sungjae: I've already got clothes and toiletries, but what else?? It's a variety show, anything can happen... I feel like I need to pack a lot more extra stuff

Eunkwang: As long as you don't just pack a luggage full of yogurt again you'll be fine~

Hyunsik: Hahaha yes I saw that episode! Last time all you brought in your luggage was yogurt and ever since fans just keep bring you yogurts at fan meetings ㅋㅋㅋ

Eunkwang: You should bring a luggage full of gold this time so your fans will get you lots of gold XD

Sungjae: Haha yes I remember that too, I've learnt my lesson ㅋㅋㅋ Do you think I should bring a thick blanket?? It's so cold outside, what if our master lives somewhere without a heater??

Changsub: If your master can sleep freezing then you should sleep freezing too!!! Whatever the master does you should follow

As the night went on, the boys chattered and Sungjae finally finished packing.

It was a busy month for Sungjae, he was already exhausted from all the promotion activities, but his schedule was packed with BTOB's concert, "All The Butlers" filming and promotions, Year End Shows and more. He was nervous for the first filming for All The Butlers tomorrow, but he still fell asleep as soon as he went to bed because of how tired he was. 

The next day, he set off to filming. Their master turned out to be none other than Jeon In Kwon sunbaenim, a famous singer than Sungjae really looks up to and respects! Honored with this opportunity, Sungjae worked hard for filming and proved himself to be a variety star. The next morning, the cast continued to spend the day with their master. They followed Jeon In Kwon sunbaenim to his practice room and requested some of his best hits. The master happily agreed to perform for them.

Jeon In Kwon: *sings "Please" emotionally*

Tears flowed uncontrollably like a waterfall from Sungjae's eyes. A drop of tear rolled down his cheek, followed by another, and another, and another, and another... Sungjae buried his face into his knees, hoping to hide his tears with his big coat. Jeon In Kwon sunbaenim's singing filled the room while the cast sat quietly in the corner of the room. Every single word of sunbaenim's song spoke to their hearts. Sungjae was overwhelmed with emotions listening to his voice, all of his worries and thoughts rushed into his mind at once, including the feelings he's been trying to hide. The cast glanced at Sungjae, and to their surprise, they saw their maknae crying. Seungi reached forward and gently patted Sungjae's head while Sangyoon wrapped his arm around Sungjae trying to comfort him. When Jeon In Kwon sunbaenim finished singing the song, they all rose to
