"Oh.. So that's the reason why.. you've been down lately."
"Yeah. It's just my vocal have been up and down this past few days and it's making me frustrated."
It is not an entirely lie. It is true that his voice were not steady so maybe that is why Jimin believes him with no doubt that he's lying.
It is far better than saying the whole reason though. Than saying that he had been sexually frustrated this past few days and that he had to jack off after their practice so that he can get over the image of Jimin thrusting in air while dancing. Yeah, it's really more better saying that.
"You should take a day off then. I'll take one too so that I can take care of you."
After hearing this, Jungkook's eyes immediately went wide.
"Really, hyung?! You would do that for me?!" His hopeful eyes makes him adorable.
"Yeah" Jimin giggles.
Maybe tomorrow will be the right time for them to confess to each other.
