Naruse is not being childish, he's just genuinely insecure about himself. He's in a new environment where he's not top dog anymore (rather, he's at the bottom of the chain?), an actual top dog is blatantly going after his girlfriend who he loves so much and is so scared to lose, and said top dog is also very similar to her previous crush who he had a //very// difficult time winning her over from. None of this is naruse's fault. He's struggling and that's ok. He's still only 18 for crying out loud! And what proper boyfriend doesn't get jealous when there are //other guys after his girlfriend//? Cut the guy some slack, he's still trying to find his footing.
first off don't get why ur so affronted by my criticisms of a fictional character. second the critic of Naruse is not only taking into consideration the recent chapters - but from the start - and all the guys that were "after" Machida (including her crush the reason for becoming involved in basketball, and Naruse's own childhood friend/rival - forgot their names) in general his way of dealing with things r kind of childish. doesn't mean i dislike him or think Machida should move on or can do better. when there's a problem or if he gets hurt he start avoiding or ignoring her, that isn't what adults do.
don't get me wrong he has his good points but he needs to grow up.
Idk what him being a fictional character has got to do w anything but I wasn't "so affronted" as you put it. Im just genuinely confused how this can be classified as childish. He's so much more mature than other //kids// his age and if he seemed childish to you, it's probably cuz he was acting his age. Like I said, he's a lot more insecure than we think, than yuki thinks, even. We have to keep in mind he's a lot younger than he seems. This chapter proves that.
more r her reactions to romantic situations, she is so freaking cute!!!(≧∀≦) lol
Naruse on the other hand, even being weirdly funny is a bit childish in his approach, especially when jealous of all the other guys after Machida.
Suwasan is a hard nut to crack, as in i don't really see clearly if he is just a player thats bored and after Machida only cause she's not interested or because he wants to one up Naruse, or if he is really in love.
Yuri is cute, and she's the typical air head but she isn't mean, and she's kind of naive, which i feel Suwasan is taking advantage of. felt bad for her when she realized that instead of her dreams coming true, Suwasan was really talking about Machida.
