I like how the author shows their vulnerable sides. It feels honest to me, somehow. I especially like how accommodating to visually impaired people their store got. Along with the character's progress in both attitude and thinking, their world slowly changes too.
Unrelated but for some reason, the part where Miku says she'll take Yotsuba's place strikes a strange memory in me. Like 1990-2000's romance anime plot that ended horribly wrong.
That look she had on page 8 totes screams "I'm recording Gojou's preciousness with every fiber of my being." Thanks much for this Christmas present. Happy Holidays!
