I actually took into consideration the time period. However, it doesn’t change the fact that most “coming of age” ceremonies were either 15 or 16 years old. The MC said she wasn’t able to have one in the previous timeline. That means there is a concept of “adulthood” in terms of romance set for that age rather than 12 years old. Of course there are always engagements or betrothal that parents make for young kids even less than 12 years. However, I guess the most appropriate judge of if it’s okay for Lippe and Hal to be entangled romantically together right now will be from the reaction of her parents if things were ever to head that way. Notwithstanding, I still find it strange for Hal not to think twice about flirting with Lippe and perhaps even hoping for a mutual relationship when she’s that young. I’m not saying that he isn’t entitled to his feelings. All I’m saying is that I’m surprised he never hesitates or is never troubled. The age difference “issue” of course would have lessen as Lippe gets older as well.
