I hope the next chapter takes a realistic approach and has her dropping the apron and locking herself up in her room, there's no way someone like her could pull through a surprise part time job on console release day.
If her "surprise" was meant for christmas, what was the point of telling him that she'll be busy the entire winter break? that just made him even more miserable thinking that he won't meet her at all until school starts again.
Sure, sure, let's just forget about the 2 weeks of depression and abandonment that made him think his girlfriend might break up with him and probably put his self esteem in the ground.
Twin tailed bitch gonna show up, spread rumors about him and everyone but the girls are gonna believe them, Reiji realizes the girls do like him, harem's back on track.
