It might be that the drawing is meant to show movement but that really doesn't come across.
I feel like Lee Bin's personality shift was too drastic. Not going to say I don't like him but I thought it was too extreme too fast from the type we see at the beginning.
Actually if you look at it closely, he has always been polite to everyone that talked to him. The only time he's being a jerk is when he first met Hwagok and he's too hungry to care etc and him being a jerk afterwards might probably be because he's emotionally constipated after so many years of being alone, and found a plaything. Once he realized he love Hwagok, he mellowed down to how he supposed to be given the chance that he could stop being alone...
There are a few scenes that's weird even for me, I agree, but overall, he's just a lonely guy that found love (๑•ㅂ•)و✧
Now that it's finished, would love an anime adaption ლ(´ڡ`ლ), and some extras.
I want to see more of the brothers losing it. Lol.
