Just marathoned the first episode of this. What did I think?
You think that it was bo...Zzzzzzz
You though it was good.
We can safely assume that it left a big impression(be it good or bad) on you, since you bothered to open a thread on it after watching.
Now, as to how we can assume that you enjoyed the show:
Only people who 'Marathon' a single episode would think that the show is good.
You just realize the VAs are Tomoya Okazaki (Oreki Houtaru) and Sunohara Youhei (Fukube Satoshi) and continue to watch only for that reason to realize it was ok.
You think you are going to hop on gelbooru and stock up on Mayaka and Chitanda porn for your faps for the next few days
You'll save at least 3 times more than you'll ever actually use and sometime during the middle some other fetish image in your stash will catch your eye and you'll lose focus and end up cumming to something completely different than what you set out to.
