I know this isn't the first and not the last story to do it, but does this happen? Do people just get up to other people and grab them? And if so how often does that happen? I know I know, it was done to save time and jump right into the issue of this guy being a nuisance. But at that point just cut to Maki going back with drinks and show Julia in the distance looking distressed with a guy or two around her. I think social anxiety is common enough nowadays that it would be even more relatable to the viewers, really.
But that's just something that bugs me whenever a situation like this occurs in a manga. Otherwise, the story was cute as heck, and if this is this author's first uh... "official"? Professional? Release, then I can't wait to see more. I could even see this get a short serialization. We would just need enough "random, extreme situations" to put them into.
