I swear to god if this turns into a tragedy out of no where, I'm gonna stop reading; I mean that's all I can do, but I'm seriously tired of romcoms turning tragic or the MC getting screwed later on.
This is pretty common trope in shounen manga too, but usually the MC is the same age. Although I do think I've seen this identical plot before in shounen or seinen.
@That-Guy - Didn't knew about that but a recent one was a guy who help a poor lil girl that get violated and punched and accept her at his home, didn't remember the title (since i read too much titles here) but oncein a while it get an update.
