Something tells me that switching to herbal medicine will stirr up problems.
Takamatsu has abandonence issues and depression, which she vents through having sex, while it does help her in some extent, it doesn't look like she went with her condition to a specialist.
People calling her "slut" have bigger mental issues than her, because her are through deep emotional trauma, their is because they were indoctrinated by toxic society they're living in and can't see how wrong they are through prejudice.
You're shaming someone who was damaged through some POS that didn't knew better.
