So technically Gyuvin had Little Space for almost 4 years now. But when he was dating Yujin, he was ashamed. So he hid it from Yujin for 2 years until......
(When they started dating, Gyuvin was 18 and Yujin was 15. Now Gyuvin is 20 and Yujin is 17.)
-at home-(they have they're own apartment)
When Gyuvin realized his little kid inside his body was about to come out, he told Yujin he was going to his room.
"Yujin-a! I'll be in our room ok?"
"Ok!"
-in their room-
Gyuvin got his box of toys under their bed. And yes, Yujin hasn't realized it since.
"Wa! Twoys!"
"Gyuvin hyung!"
Yujin called again and again but no answer. So he went to their room to see what's going on.
"Gyuvin hyu-"
"Daddy?" Gyuvin said as he almost cried as he thought he was mad at him.
"What?"
"I'm sowwy"
"Sorry for what?"
"Dwon't knwow."
"Come here. First, I'm not mad. Second, Don't cry. Lastly, come here"
So Gyuvin ran to his(Yujin's) arms.
"Hyung-"
"No Hyung pwease."
"Then what do you want to be called?"
"Gyuvinnie, Bwaby or Little Puppy"
"So Gyuvinnie, can you tell me what's going on?"
"Swo 4 yeaws agwo, I had wittle spwace."
"Why didn't you tell me?"
"Becwause I was ashwamed (ashamed), thwought you would be mwad at mwe and thwought you would leave mwe"
"Can't you see? I'm not leaving you not matter what. I'm still going to love you the same. Ok?"
"Owk!"
