I remember the first time I read this volume it kind of took me out of my happy sunshine overly sweet adorable vibe I was rocking after the other volumes, and I was disappointed by that because that vibe was what I needed at the time. Once I read it a second time I knew I did actually like it a lot too, and this time I loved it AND was surprised about storylines in S2 that I forgot were from this volume! Vol.4 focuses on the harder parts of life and a relationship, and how to learn and grow and help each other. It's REAL life. CW: one MC attends for eating disorder and mental health diagnoses and treatment, and there are mentions of past self harm with no details.
