how do u imagine their morning after
well technically this is their morning after
but I can imagine Kaneki waking up like that to the feel of Touka running her fingers through his hair. Looking up to give her a sleepy smile before realising… they are both naked… and /that/ happened last night *INTENSE BLUSH* then stumbling around awkwardly to find their clothes. Kaneki loses his underwear until Touka comes across them and puts them on his head.
or OR if you want to go the fluff version, maybe when Kaneki wakes up Touka is at the window [x]
He goes over, puts his arms around her and his chin on her head and they just stay like that for a while, breathing it in
