It cannot be considered invest as such because they're not related and no, she won't end up with the original husband (spoiler: Eugene never took her down the wedding alley because he could not stand her marrying someone else even back then). I believe that she'll be readopted by the original husband's family so there won't be a problem. Not to mention that in those times, siblings and cousins married each other a lot.
so she's gonna end up with Eugene right!? OMG IM SO HAPPYYYYY EUGENE IS THE BEST BOI I CANT IMAGINE HIM MARRYING SOMEONE HE DOESNT LOVE AAAAAACK
Yes, that's what I heard. It's implied a lot in the story actually ^^
Fine, point taken I'll ship the two of them (づ￣ ³￣)づ
Oh ahm, not to sound like I was forced (since I wasn't) that's just how I talk... •*•
