This movie was very similar to Train to Busan but unlike Train to Busan which was superior to this movie, this movie had one big plot device in the little girl. I mean, the entire plot revolves around the little girl ie. when she gets lost, having to save her, etc and at one point, it starts getting redundant. There's also a K-drama-like romance between the main leads which annoys you as a viewer coz here's a guy who does so much for the female lead but she shows no appreciation or gratitude throughout the entirety of the movie. The female lead was literally a cold bitch to the main lead who was saving her ass and her daughter's time after time and it made me wish her death in the movie due to how utterly annoyed I was at her personality. She was so selfish to the point that she basically put the life of the kid who survives the infection and has anti-bodies to cure the disease all to save her daughter. Not to mention how she literally tells this kid to stay alive as he's about to die after being stabbed just so that she can use his anti-bodies. When the female lead got shot in the end during the climax of the movie, I was happy but then I realized that she was shot in the shoulder and its only a flesh wound and not fatal. Which reminds me of how predictable the movie is during the end. Its not gonna make you cry or anything unlike Train to Busan did. What I love about Train to Busan is that it explores the struggle of a father and daughter through a zombie apocalypse on that train and it doesn't use the daughter as a constant plot device like this movie does to the point that it becomes annoying. If your're having second thoughts about watching this, watch Train to Busan instead of this K-dramaish movie about a flu infestation and a very annoying female lead.
Why is Japan so obsessed with student-teacher relationships? I get it that they view everything differently compared to the rest of the world like age in relationships, etc. but the amount of cliched and generic student-teacher Jdramas is almost endless and this one is no different. I don't even know why they bothered making a reverse harem outta this when the other two love interests are nothing more than side characters and the main love interest AKA the student gets the most of the screen time. Hell, the very plot is Junko teaching this kid so why bother making it a reverse harem at all when its obvious that the student's gonna get the girl aka teacher. Not to mention the dramatic cliches there are in this show like the girl falling down the stairs and the guy catching her. If you want your typical cliche student-teacher Jdrama, then this for you but if that sorta thing is not your cup of tea, then might I recommend you to not watch this. I was actually shipping her cousin with Junko who was in love with her for 20 years and was kinda pathetic about it to the point that you felt sorry for him despite his success in life. But as cliche as ever, the childhood friend never gets the girl in both anime and Jdramas apparently. The other two love interests other than the student were actually part of her childhood which make them another victim of the childhood friend rejection trope. Either way, I dropped it after episode 3 when I realized how plain and obvious it was that the student was gonna end up with the teacher due to the other two love interests barely getting any screen time at all. I mean, if you're gonna have a reverse harem, at least put some character development in the love interests instead of just pushing the main couple. Isn't the point of a harem to keep the viewer guessing who the protagonist is gonna end up with? Well, this show totally fails in that aspect!
