It's a shame Misuzu didn't get with anyone in this manga. She deserves love considering how much she helped her two friends even though she didn't really like the idea of Tomo and Jun getting together.
I like alcohol filled chocolates quite a lot, but only when the alcohol content is low and it's sweet liqueur. I have eaten those with hard cognac, whisky, and such, but I'd call them barely edible. Who knows why Carol bought ones with such hard booze. Seems like Misuzu does like her drinks, though. I can easily imagine Misuzu's mother enjoying them, and those two are very similar.
