So the blackmailer just stops out of nowhere and then all of a sudden the MC and Tokimori are sleeping in the same bed.
Are there pages missing from the middle of this chapter? Like 20 of them? Cause that was a hell of a shift.
Also the whole "but people will think we're in an office romance!" thing is dumb because we've been given no indications that office romances are forbidden especially since while Tokimori is a senior, I don't believe she is nominally his boss (the one situation where them being in a relationship would actually have significant issues attached.)
