[Shun would probably try to inspect him more closely, but Ren dragging himself even closer makes that somewhat difficult, especially once he sticks his face into Shun's shoulder. The whiny complaint does get a faint snort out of Shun, though, however harsh it might sound in the wake of still not having given himself time to eat or drink anything. It's also audible in the slight scraping and quietness of his voice when he actually speaks this time.]

This is already later than I usually make you get up. [And while he (probably) isn't currently up to dragging Ren out of bed himself, he instead wraps his own arm around Ren's waist and the other around the back of his shoulders, then rolls over onto his back in hopes of dragging Ren along with him.]

But I'll give you a chance before I roll over the other way instead. [Flattening Ren is still definitely a valid way to wake him up.]
