I think a possible interpretation for what the mangaka tried to make was that the boy noticed the girl from the start and that goes one through the one-shot. I mean, no one else noticed her leave, and that shows he spares more attention to her than the rest. The moment he notices her is the moment she "grows up". She hides her shame by throwing the swimsuit away, but he finds it out of sheer curiosity, and is quite disgusted/scared by it, which I'm not sure which because there are no sounds that indicate more of his reaction. To me, either he's scared of the blood in an innocent, childish way of a boy that doesn't know how girl's anatomy works or he's disgusted by the symbol of her adulthood. Either way, then he learns that her dad is abusive, and then again, he's worried for her, but his parents seem to be indicating they don't want to meddle and he should also stay outta their business (which also contributes to the not liking adulthood angle, since the adults SEE but choose to ignore). But he keeps looking out for her, and she goes away with her mom. That time, is the first time they meet eye to eye in the one-shot. I think the big close was chosen to emphasize the expression of her helplessness in the whole affair, and of course, she's pretty, I think it hints he quite fancied her. Remember in the pool people were joking and playing, and only he noticed her, as she turned adult? Welp, his fixation also seems quite part of his growing, yet, like the swimsuit, he isn't quite ready to accept all aspects of growing. Anyway, I think, still in this childish mindset that he thinks the swimsuit has anything to do with her going, so he returns it in hope she comes back. But he realizes or admits to self that it's not that at all when he's leaving. He gets the swimsuit could be a metaphor for him accepting his adulthood as well. Anyway, he understands she isn't coming back and throws the swimsuit at her door possibly:
1) understanding that she didn't leave because of the swimsuit, but because her father was a jerk, therefore, reacting angry towards him, showing the understanding of an adult but the defiance of a kid (different from his passive parents), in the process of growing;
2) understanding that she, whom he liked, grew up, and his fancy towards her made him notice some aspects of his own growing up; that said, he angrily throws the swimsuit at her door because he is mad at her for being the first thing in his path to adulthood.
Either way, he's probably mad that although he notices (and probably resents) his adult side, he is also as helpless as she was being taken away. Not being ready to grow in this case could mean... not being ready to accept the impotence of adulthood.
BUT, it is badly executed. lol the panneling is very stiff, the spaces between images don't convey the passing of time, the expressions are very ambiguous and at least to me, morals seem very input in the end of the comic, like... "that's what you need to know", leaving less space for interpretation. Didn't like it. Yet for the analysis... I was bored? (￣∇￣")
I love your intepretation on this! Makes more sense, so thanks a lot (▰˘◡˘▰)
i feel like i went to college and graduated reading this god bless you soldier
What I got from the manga was...a boy noticed that his neighbor was upset pool and it turned out that she had her period In her swimsuit. He noticed her throwing away a bag and it turned out it was just her bloody swimsuit. Then the boy finds out that the father was abusive to the girl and her mother but the mother was like...I'm not about it anymore and left with the girl. The boy then went into the field to get the swimsuit and threw it at the abusive fathers door....insert symbolism here
