I also planned to include a stockpile about how utterly dysfunctional everyones families seem to be. While Charlotte's is a no brainer, the Sarashiki's are my main target. This is emphasized by the fact that Chifuyu's childhood friend (Male or female) is a Sarashiki with abandonment issues due to not being related by blood and only there because parent married in.
Besides, can you even imagine her being friends with Dan?
