I'm so done with Hiroto. I think the story attempts to make us sympathize with him but it's just not happening. I don't feel an ounce of pity for this winy, selfish, self-important brat. He only knows how to blame other's and repeatedly play the victim card. Yea, his situation may have been upsetting, but it's not like there's an evil plot to ruin his happiness. In the original timeline it was Hotaru's choice to end things and in this timeline they're not even together yet and he's already flinging out accusations.
I think I've also said this before but his feelings for Hotaru feel much more like obsession rather than love. The guy is scarily fixated on her. From the way he can't let go of a girl he only dated a short time, to the fact he lashes out on anyone he sees as a potential threat to a relationship with Hotaru, and his inability to own his own feelings, are all huge red flags. At the rate he's going it makes you wonder what he'd do to her if they did end up dating but she decides to break it off simply because she's not into him anymore. Or what if she decides to date some other guy? I wouldn't want this creep anywhere near my sister much less matchmake them. Hotaru deserves not just better, but putting her with him would honestly be a curse on her life. They would need to do time travel all over again just to save her from that nightmare.
