How you celebrated his birthday
Renjun
You had a small party of only immediate friends, but you also celebrated with family. Two parties. At the friend party there were games and the older members were drinking, but not the younger ones. People were doing karaoke and popping streamer canons. At the family party there was traditional Chinese food and you met his parents. A chill birthday.
Jeno and Haechan
They seem like surprise party people. Jeno because he likes fun, obviously, and Haechan loves himself, so why wouldn't he want a party in his honor? Haechans party would be extra. You would get everything made with his face on it, even the cake. Everyone in NCT would have to sing his birthday song, and he expected it done well. Not only that, but his presents had better be top tier as well. Jenos party would be more chill. He wouldn't care much about what the decorations looked like, as long as everyone was having fun. He preferred money as a gift because there was more flexibility with what he could do with it.
Jaemin
You gave him a really cheesy gift, and then went out for a day of fun. You started with a morning date, because he liked to go drink coffee. Then, you went to Han River and had fun there. That was a chance to keep him away from the dorms so the boys could set up a lil birthday dinner action. All in all, he was really happy with it.
Chenle
You two went to China. You didn't plan this trip, he did. He insisted that what he wanted for his birthday was for you to know more about his life in China, so he took you to meet his friends and family, and see his house and the places he grew up.
Jisung
You spend the whole day together, but unlike Jaemin, it was just the two of you. He was with the boys so much, he just wanted a day alone with someone else that he loves dearly. You weren't really sure what you were going to do yet. If he was tired from work you would spend the whole day cuddling and lounging around the house. If he wanted to get out you would go into town and do whatever you wanted. It was his day, so you left it up to him.
So about NCT Dream, I kinda like ot6 because Mark is in way too many groups already (he's probably exhausted), and the other members could get a chance to showcase their talent more. What do you think?
