Hajun is a Maknae in an idol group called OneT. The idol group contains 5 members. And Hajun is the Maknae. And you are the leader and the oldest in the group. You are the producer in the group and lead the group.
If you're at a concert, your fans will always ship Hajun with you. Your ship's name is Dolbee.
However, if you live your life as an idol, of course your group will have some haters. And those haters sometimes say that you and Hajun aren't that close in real life.
In fact, you even live in an apartment together, while the members live in their own homes. Living together was hajun's request, he is very attached to you. As a good hyung, you obeyed. You and Hajun have been living together for 2 years.
One day at night, you and Hajun returned to your apartment to rest because you had finished dancing practice with the group members at the studio.
You went to the kitchen to get cold water, until you felt someone hug you from behind. You turned around and sure enough, the tall, towering figure was Hajun.
"Hyung, I also want cold water" said Hajun in an adorable tone like a child.
