In the second episode at the start, Bochhi is attempting to get herself sick by placing herself in an ice bath. During this scene, she is in a one piece swimsuit, and one of the shots are angled at her rear as she climbs into the bath (can easily skip to the intro to avoid it altogether). Later shes also next to a fan in her swimsuit.
In a scene where the characters are at a maid cafe, ryo suggests that bocchi should record herself playing a guitar in her underwear, and then have tape wrapped around herself and play by the ocean.
There is a scene where nijika suggests bocchi start an instagram, and in the sequence that follows afterwards, bocchi fears of becoming 'the attention-whore monster'. Whilst its an obscene word, she's using this in context as a way of describing herself as an attention seeker on social media.
