Hunk owns a bakery and Keith opens up a coffee shop with Adashi across the street. Lance doesn't work at the bakery, but he's very supportive of his best bro. He's worried the coffee shop will start stealing their customers, so he tries to disrupt them.-

-Nothing evil, just annoying things like sneaking in and flipping their "open" sign to "closed", hiring an Elvis impersonator to sing outside the shop, putting a For Sale sign on the front door. He loves seeing the angry look on Keith's face.-

-He also just likes looking at Keith's face. He has a very pretty face, but Lance is in denial about it. ("He's my rival!" "Rival for what?" "He's gonna steal all our customers, Hunk!" "Lance... you don't even work here." "Hunk, I can't believe-!")-

-Things escalate when Lance goes a little too far one day and accidentally breaks a window when he's shooting his nerf gun. He feels immensely guilty so he goes over to apologize. As soon as he walks through the door, he's hit in the forehead with a dart.-

-He looks up when he hears a sharp laugh and sees Keith peeking up over the edge of the counter, holding a nerf gun.

"Payback for breaking the window."

Lance winces, embarrassed.

"Fair enough." He says with a smile.
