[DATE] Tanin ni Naru Kusuri 4.2

Every few days, without warning, Ishii Yuto finds his mind pulled into Fukusawa Marin's body—stripping down for a bath only to meet a stranger's reflection and realize the medicine meant to help Hoshina has made him her secret tormentor instead. Trapped in borrowed skin and haunted by memories of the frightened, docile girl he cornered, he surrenders to a guilty arousal he swears he'll resist next time, whispering apologies and confessions of love between waves of pleasure. The vows to protect her and to bully her again blur together until he passes out, utterly saturated with someone else's personality.
