I think I can guess the general flow of this comic... Satori's worrying about what happened in a previous comic, says she loves her too (or that she loves someone), finds Koishi's been watching, asks how long she's been watching, and Koishi takes the mickey out of her with glee.

I love you"Eh~?H-...how long have you been here? outpour
