Each character goes through themed story arcs with breaks in between. This naturally means a build up, a peak, and a come-down. Lin in v0.18 and v0.19 is at the peak of her current story arc.
It's not uncommon for me to hear "There's too much drama right now, when will we get slice of life". But some seem to forget that they are actively witnessing me writing a story. We're not going to stay in the height of the current arc forever!
Don't worry though, catharsis is an important feeling for me.
