AH! I feel like I've read this before but I can't find it. This is the only one I can find with a similar chapter. But I don't think its it. (The scene is in the last chapter)

There's this manga I read and this was a certain chapter.
Basically the uke tried to wake the seme up in the morning and the seme looked grumpy and scared the uke. The seme washed up and everything and realized what happened so he rushed to the uke and apologized telling him that he wasn't a morning person.
