so in this chapter...we pretty much got everyone involved, know and Support Ichikawa's and Yamada's relationship? her friends know, her Father is okay with it (especially after seeing the PE jersey he was wearing) the dad probably thinks hes already going to be the Son in law and treats him that way (by playing games with him). Even the mother is okay with it.
and Moe does seem serious that she is indeed friends with Ichikawa huh. thats good. with people now backing them for support, what else is gonna push them to confess? probably graduation
