Wait, so FMC and her ex-friend became friends again? Looks like they're talking to each other, but with a note like 'read the original three volumes', as in the LN this series is based off of, I can't imagine how they got to talking again if they couldn't show it here.
Anyway, the series ended up pretty bland. It's not bad, but not good either. It had its moments, but it's not worth raving reviews imo. It's like the author barely added seasoning to something previously tasteless to make it safe and edible. That's probably the best I could describe it. MD will round this to 6/10, but it's more of a 5.5/10 for me.
