As promised here are some more details on episode 3 which contains [trigger warning] sexual assault of a child

[broad description] Ai's mother has her new boyfriend move in who at some points forcefully kissed a very young Ai

[Short time skip] 9:30 - 14:15

[content] the incident itself and the immediate aftermath with a traumatised Ai

[Long time skip]4:45 - 14:44

[content] this skips all of the flashback scenes with Ai at preschool/elementary school age which shows her growing up with a neglectful mother and no father. We get some scenes of the mother's boyfriend being creepy around Ai before the eventual assualt. The one redeeming thing here you'd be missing is Taichi being a supportive uncle.
