Despite Usui trying to act cool, the fact that he's actually an insecure boy with a jealous streak is adorable that I honestly wish it's called out more. Though he did seemed to call himself out, even jokingly for what he's doing. The highlight of this episode is definitely the bond between best friends that Misaki only have with the two girls and the way she became vulnerable with Usui because he is the only guy to rely and criticize her honestly.
