yes, as a possible option. but, if you remember, on the train (on the way to the bathhouse) there was a scene where MC fucked Tomoe without penetration (I mean assjob + tightjob), and there was an option to leave Tomoe at the mercy of the rapist. maybe "hand over" (turn into a public whore) - this will remain an option for the path of "evil karma" (not my path, to be honest) - I don't know, I can't look into the brains of irfaeus, but maybe for the path with neutral or by good karma, Tomoe will remain his house sex maid.
but Tomoe is not the "boss of the game" but maybe the "level boss". The "boss of the game" is most likely Hiroshima. with her arrest, as a result of the investigation, the slander on the father of the protagonist will also be revealed, and it may be possible to take the academy into MC's own hands.
