Chapters like this remind me that Happy is actually quite well-connected socially. Everyone loves her!
Reading this manga is the definition of "it's so over... We're so back!!", over and over again.
It's interesting how, outwardly, Happy doesn't act that different from Hanazaki. Both are very receptive to the wants of others, and they're really kind people. I think having Hanazaki is great for Happy, because just by offering her support, he is putting an end to her spirals into madness; she doesn't need to force herself to feel happy. Similarly, Dante is a very nice influence too.
