As someone who has anxiety and is also dating someone with anxiety and low sense of self-worth, I think this was a surprisingly accurate depiction of anxiety in relationships. Even the smallest, slightest detail can set it off, and they lead to these rapid 0 to 100 thoughts of what a terrible person you are. This chapter alone earns the manga an easy 10 just from how raw and unabridged the message the chapter is delivering feels to someone who's dealt with both sides of an anxiety relationship.
