My theory is that Osana is pregnent. Osana had to do the same thing as kokona and do compinsated dating. She got pregnent because of it and now she has a kid inside of her. She wants senpai to not worry about her and so she has to keep it  a secret. The man on the call (or woman) could be threatening her to give them the son/daughter or they will tell senpai.
