The boys were practising for their upcoming showcase on April 4 that will be held in Japan. While on their break Jinyoung asked Jackson to accompany him outside to buy some foods.

Jinyoung: hey my friend 
Jackson: Wae?
Jinyoung: let's buy some snacks
Jackson: Assa! 
Yugyeom: Hyung I think Suzy noona is right. You are a pig 
Jackson: Yah! Aish Suzy is such a bad influence
Bambam: Ani she's just saying the truth
Jackson: yah waegurae? 
Mark: Just go 
Jb: right! Go buy some foods pali!!
Jackson: whaaaa jongmal! Why are you like this?
The boys didn't answer. Jr and Jackson went out. They were actually doing that in purpose they wanted Jackson to go out with Jr so that they can plan for his upcoming birthday which is on March 28. Jackson is someone who loves to goof around, he jokes a lot but when it comes to people around him he always wants to be noticed by them. In other word he loves it when someone shows their love for him so the boys decided to surprise him on his birthday since it'll be his first birthday with GOT7. 
Bambam: hyung otteokeyo?
Jb: nado molla
Mark: Even if it's just simple I'm sure Jackson will be happy. 
Yongjae: Let's invite Suzy noona
Jb: Maja, since those two are frenemies.
Yugyeom: but noona is busy
Bambam: Just ask her first maybe she doesn't have any schedules that day..I also want her to come..
Jb: Hyung why don't you call and ask her!
Mark: Me? Arraseo
Mark dialled Suzy's number. He called her twice but she wasn't picking her phone
Mark: She is not answering it
Yugyeom: I told you Suzy noona is busy right now I heard after their Hongkong concert there will be Beijing concert too. 
Bambam: Jinja?
Youngjae: You didn't know? Aigoo I thought you really really like noona
Bambam: ne I really like Suzy noona wae?
Yugyeom then asked him the hardest question 
Yugyeom: then who do you like Suzy noona Taeyeon shi?
Bambam: Yah how could you ask me that question!
Mark's phone rang. Suzy was calling him.
Mark: It's Suzy
He answered her call
Suzy: Oppa mianhe I didn't know that you were calling me
Mark: that's okay... where are you right now?
Suzy: Filming site. Why did you call oppa?
Mark: ah are you free tomorrow?
Suzy: oh jangkaman
Suzy: manager oppa do I have something to do tomorrow?
Her manager checked her schedule and told her that she has to film a cf at 1pm- 5pm. Suzy said thank you to her manager and then talked to Mark again
Suzy: I have to film at 1pm-5pm after that I'm free. Wae?
Mark: It's Jackson's birthday. Do you think you can come?
Suzy: ohh jongmal? Yes I will come

Suzy: Annyeong oppa 
Suzy ended the call
Mark: She's available at 6pm
Jb: So she will come?
Mark: ne
Youngjae: Yehey
They planned on how to celebrate Jackson's birthday. They decided to do it in Jyp building since they really can't go outside to celebrate it.  Aside from Suzy they are planning to invite some friends. They finished their surprise birthday planning before Jr and Jackson came back.
Jackson: why do you look strange?
Mark: us? Says someone who does look strange every time
They ate as if nothing happened Jackson didn't mind them anyways. He was actually expecting them to do something for him. He was also anticipating what will his fans do for him.. They continued practising after eating. When it was already time to go home Jb said that others can go home but he will be staying with Mark. They have to decorate the place and he didn't want Jackson to suspect them so they decided that Jb and Mark are gonna stay. After leaving, Jb and Mark started to decorate the room. They put some party hats around and they sticked "HAPPY BIRTHDAY JACKSON"on the wall. While decorating the room someone entered without knocking they were surprised, they thought the boys came back again and that their mission will fail. Upon seeing the person who entered the room they both breathed in relief. It was Suzy wearing a hoodie and a face mask.
Jb: yah you scared us
Mark: what are you doing here?
Suzy smiled 
Suzy: I brought some balloons. I want to help
Jb: daebak! That's good how did you know we are here?
Suzy: I asked manager oppa and he said that you two are still here decorating the room. So I decided to come. Let's go
Jb: let's go
Jb started pinning some letters, Mark was inflating the balloons while Suzy was busy sketching Jackson on a piece of paper. After looking back and forth from Jackson's photo to the sketchbook, she finally finished sketching him.
Suzy: it looks the same right? *proud
Jb and Mark looked at the portrait with an awed face. The sketch looked exactly like Jackson. They were impressed by her talent.
Jb: waaah Suzy yah if you are not an idol you can be a painter daebak 
Jb's mouth was wide open while giving her a two thumbs up
Suzy: thank you
Jb: next time draw me too
Suzy:
