at this point everyone know he will either die in battle with "old" seol-ah or convince her to live with him in the future again so he will leave the present...
idk, i still think that it was all a misunderstanding, and mahiru and kiku died bc of the sunlight and not bc of love, also since nazuna is a special case i dont think the "love rule" will work on them (me and a friend were talking about it and we think that in the end they will both end like half vampires or something like that)
I think we're about to enter the final arc, she's going to disappear from town for fear of making him disappear, so he goes after her and when he finds her there will probably be some plot twist so they don't have the same ending as mahiru and kiku- san
