Yeah - I’m really curious to see where this is going to go. We can be sure that it’s not going to be heartbreak and betrayal, nor is it going to be a throuple or reverse harem, because this manga is far too wholesome and upbeat for anything like that (not to mention this is the youngest sister). But we can also be pretty sure, just based on what the author’s already done along the way, that it’s not going to be simple and predictable either.
