it's a bit annoying but feels necessary for Tohno to face those insecurities. And like. Houjo and Rei would need to talk at some point lol, like this is a romcom Houjou and Tohno are the main characters so they gonna end together and it's like... When they start to date should Rei hide if their family ever invite Houjou for something? I get not becoming best friends, and sure Rei can just go do something and keep avoiding but like... They would need at least say hi sometimes. And this entire conversation they had here was mostly small talk that like... they got a bit excited and happy because they talking about someone they both love?!
The whole reason why Rei is there is cause he genuinely interest in trying backstage work. But during it I don't think Rei would be in the wrong even if he actually went to talk with Houjo and wanted know her a bit more, i think it's fine wanting to know a bit of your brother's friends? Not a must, but a normal thing to want??
BUT HERE IT SEEMS HE ACTUALLY REALLY WAS JUST FREE?! He even got there before Houjou, should he give up helping in this task cause she was free too? Or should they be completly silent while doing it ?? No ofc not, since they both ended there why not chat during those 5 minutes doing the task?!
I do get the protagonist being a bit shaken cause he never really got rid of those issues but they didnt do anything wrong at all, so feels a bit silly for some readers act like Rei is in the wrong <:/
