I refuse to believe Saki didnt know about boys intentions. Chika was just being a busybody and ruined Saki's hussle for a free ticket.
This development mildly annoyed me tbh. There's nothing wrong with going to the concert with that boy. The ticket was a no-strings offer, a free gift. If he secretly expects something in return, that's his problem and Saki is not bound by any of that.
Chika acted in a way you see a lot in mainstream boy x girl romcoms. The girl has a chance to do something that she likes or that is good for her but that will also make her closer to other boys in the cast, so the mc boy sabotages her plan (without explaining his reasons) and afterwards keeps pretending he isn't interested in her. This always struck me as perfectly crappy. If he cares so much he should ask her out and start dating her; only then he would have valid grounds to tell her to turn away other guys. This is what Chika should do if she wants to stop Saki from getting too close to other people: claim her! Not get in her way with half-assed excuses.
As the other fellow said, there are no true free lunches. You don't have to give anything you don't want to, but it avoids future trouble to avoid setting expectations you do not want to fulfill.
I agree. In both the mc is a girl who never before even imagined the possibility of going out with another girl, but then found that, indeed, it is a valid option... and now gets nervous and dokidoki every time she's around her best friend and totally doesn't know how to handle it, hehehe.
