DO I EVEN NEED TO EXPLAIN WHY THIS IS WONDERFUL
If you look at the "Riverdale | Riverdale Season 1 Photoshoot | The CW" video at point 0.07, you can see LiliCole standing beside each other in the background looking at some device (camera?) + snacking. Also Cole (not sure about Cheryl) is the only young cast member not in the background at point 0.01, when Lili is doing her solo photo shoot, which in my shipper mind means that he is up front watching her pose. Think he may sneakily have his hand on her right shoulder or back at point 0.25.
