Soobin tested his theory the next day.

They finished dinner and he let the others go because he felt like they had done good today, and he could handle a few dishes. Beomgyu stayed just for the sentimentality but he ended up not doing anything, simply talked with him until Soobin saw through it and shush him away. Beomgyu didn't even argue and left, his laugh ringing obnoxiously through their dorm.

Yeonjun came back, though, he said he went to his room just to get his phone. He placed himself beside him and started helping, his hands covered in foam.

For a while it was silent, just them cleaning the dirty plates, until Yeonjun spoke.

"That was sweet of you. To let them go. Even when they're brats."

"Yeah, well." Soobin shrugged, feeling the telltale of a blush creeping to his neck at the compliment. He wished Yeonjun wouldn't notice. "They practiced hard."

"I know. They really did."

"You did too, you know. You didn't have to help."

"But I want to."

"If you insist."

Yeonjun nudged his shoulder with his. "You practiced hard too. Who's going to take care of you if you're too busy taking care of us, hmm?"

Soobin's face heated up involuntarily, like it always did when he was on the receiving end of Yeonjun's attention, but he let out a soft laugh. "You need to stop that. One day."

"Stop what?" It was there again, the teasing, wrapped around his voice. Soobin didn't understand why it was attractive to him - the cockiness, the confidence, and even when he was looking at the overflowing water, he knew Yeonjun's eyes would be glinting.

"You know what, hyung."

Yeonjun didn't answer but he laughed at him, spraying him with the foam on his hands, the soapy water drenching his own sleeves. Soobin splashed him with water to get him back and it turned into a fight - Soobin closing his eyes to avoid getting soap in his eyes and his hands holding Yeonjun in place.

Yeonjun was stronger than he looked and it was difficult to make him stop attacking him with the fucking foam, but in one brave second, Soobin opened his eyes and pinned him against the sink.

The attack stopped almost immediately.

Soobin's hand was placed on the sink just beside Yeonjun's hip, and the other is circled around Yeonjun's wrist, holding him still.

When he looked up, Yeonjun was blushing.

The pretty red on his cheeks came back, just like yesterday, the same image Soobin couldn't get out of his head last night.

Yeonjun's lips were parted again. Plump, crimson, inviting.

Soobin just needed to lean in, he realized. He just needed to lean in to capture him in a kiss. And he wanted to.

But he didn't - he was too busy staring at Yeonjun's blush up close, the small puff of breaths he let out, like he was nervous.

Soobin marveled in it, by how pliant Yeonjun looked, that he didn't even need to hold his wrist with much power anymore because Yeonjun just let him.

"Soobinnie..."

That voice wasn't teasing anymore; it was soft, in a whisper, like a plea.
