What if Luhan accidentally left a tshirt at the dorm, in his old room. And one day Sehun walks into his old room, and is trying to find something for another member but sees a bit of familiar fabric poking out from under the bed, He goes towards it, plucking it up off the floor, and quickly realises who it belonged to and he broke down in tears, hugging the tshirt to his face.

And then a couple of days after finding it, he starts to wear this tshirt, remembering how he felt when Luhan hugged him, and how much he missed his hyung.
