Manga:3

Woodstock
꩜。⋆A girl on the shore ⋆˚꩜。⋆
Two teenagers, marked by a recent trauma, having sex to escape their boredom and loneliness. I've read many comments on reddit, youtube, and other sites of people who disliked it and why. Most of them said the sex scenes were unnecessary and that it made them uncomfortable. Some others said that the story was plain, that it didn't have a solid meaning. And hey! I know it isn't for everyone, but I practically became obsessed with it. It's been about two years of me going on and on about how much I love the story and how I connected to the characters- especially Isobe.
The manga includes topics such as abuse, suicide, “chuunibyou” (teenagers with grandeur delusions), bullying, and other stuff I can’t even remember or want to mention.
I get depressed every time I read this manga, yet I keep re-reading it. The sighs, the words, the feelings. Everything is depressing. Isobe’s brother is a key character although he’s never actually in the story. However, his interests are always present: Isobe looks for his own essence using the pieces that his brother left, which Sato will later take on. It’s difficult to explain, but when someone else’s interests become your own, a deeper connection is created. As the youngest sibling, some of my interests were acquired from my older siblings. Watching or listening to the things they like makes me feel closer to them somehow. Anyways, I once heard someone say this story was (to make it short) “Depressing teenage sex” and I totally agree! If you’re sensitive to certain topics of images, I would not recommend this. And! If you’re interested but can’t have a physical copy, there is a copy on the internet archive (Umibe no onnanoko).
P.S There's also a movie.
