DO/Jungkook Oneshot

Jungkook ran out of the shower, wrapping a towel around his waist, jumping over JHope on the floor to step out in the hallway. He watched the frightened DO fight to open his hotel room door, finally having Chanyeol open it and DO falling in. Jungkook just looked down, his face still red. What was with him?
JHope was slowing getting to his feet, "What was with him?" He asked Jungkook, just looking down at his stained shirt. Jungkook just looked longingly at DO's hotel room door before walking back into his own room, debating whether or not to tell JHope what DO did.
"I don't know."

Meanwhile, DO was curled up on his side, trying to hold back tears while Chanyeol asked for the fifth time what was wrong.
"I'm fine, Chan, please go to bed," DO finally stood up to go to take a shower finally. He brushed past a downcast Chanyeol to lock himself in the bathroom.
Chanyeol just sat on his bed, using his towel to brush through his still-damp hair. He knew DO well enough that something was very much bothering him; he never acted like this. Was he sick? Were there family problems at home? Was he...in love with someone?
Chanyeol sat up again. DO was in love with someone, it had to be the only explanation. He had never seen DO like this before.
But...with who?

Notes

Imagine Chanyeol here tho
