Tonari no Furi-san ga Tonikaku Kowai
Danna ga Nani o Itte Iru ka Wakaranai Ken
Hachigatsu Kokonoka Boku wa Kimi ni Kuwareru.
Super interesting, a little heavy on the Yandere stuff but the atmosphere is so perfectly creepy, I'd recommend
Boku no Kokoro no Yabai Yatsu
I love this one, pls read it. Its a little heavy on the ecchi-like moments but that's expected in shounen romance, and there's plenty of pure moments and slow relationship development to even it out. I recommend you read the manga over watching the anime, I feel like the anime made him much more shy and less edgy, taking away a good amount of the dry humour I love about this manga, plus I like the way the mc is drawn in the manga more than the anime. He's a little more stylized here and it emphasizes how he doesn't completely fit in. In the Anime I feel like they to away the stylized way he was drawn.
