this cant be a former victim, the timeline just doesnt add up. the MC and the mom have been together for years, and touko and the MC have known each other since she was in middle school. i would estimate the MC and mom have been together for 4 years and touko and the MC have been acquainted for 2-3 years. it could be longer, up to 5 years (first year middle school, second year high school is aprox 5 years). theres just no way a 12 year old or younger touko was trying to have a baby (or scam or murder or sacrifice to satan, whatever the theories are) with this guy. i actually hate this development, guess we will see more next chapter.
