I'm Pretty sure the Mom 100% knows they are dating, no fucking shot that adachi who's been over Shima's house several times, eaten with her, took a bath with lil sis, picked up Shima to go to school already and was cool with it BUT the second after the confession she shows up hella early waiting to pick up Shima which is different to regular picking up Shima in time, your telling me she didn't notice the change? nah 100% knew it hence why she's observing Shima's new GF also waiting for Shima to open up hence why she used Good Friend instead of outing her
Also there's no fucking shot that she hasn't heard all of Adachi's loud outburst like "I'm looking forward to this relationship, I wont let you down" etc etc

I bet my ass she was 100% out the door hearing all that shit outside and then popped out asking if Adachi ate breakfast to inv new GF and observe her
