If there is anyone who is useless and a waste of screentime it has to be Mei, or rather her character just screams of the annoying "dumb bitch" trait I have grown to hate. In fact it would be way better to have her confess to Layfon to be shot down and removed altogether
But it seems like a new challanger is being overshadowed and may appear in the near future to stirr up some "shitz"
Whereas Mei was being annoyingly nosey/fangirly/flustered etc towards Layfon's latter, I prefer Felli's more silent approach. You don't necessarily need to go over the top to show emotion like what Mei is doing, in fact I feel that Felli is being more "deep" in that sense of being quiet in her own little way.
Oh and not to mention the extremely funny cooking scene and the consideration she showed when she held back from kicking Layfon who was holding a knife. Sulky face is moeeee
Nina on the otherhand is being deeply screwed by an inferiority complex towards Layfon she is developing. This could become a problem if she becomes jealous of Layfon for being better than her causing her to do something to harm him in blind jealousy.
Hopefully she will snap out of it soon.
