You know, I'm still prepared to believe this whole thing with Jake is just one huge misunderstanding. Like, he is not stalking Yuri, but actually shadowing her to protect her. Or he's making photographs for her father who wants mementos of his darling daughter. Something silly like that.
And then Melissa finds out Jake isn't interested in Yuri at all, but was a tsundere sis-con all along.
I might be completely wrong, but I wouldn't be surprised if we have at least one twist regarding the love interests coming our way.
