just finished reading a shonen ai insest between brothers and need more, so could someone recommend me a yaoi insest of brothers, but not the traumatic kind traumatic/ psychotic that involves rape and yandere but a story where sex is consensual, where the main characters have their doubts and fears, something with character development, something like Ani No Chuukokuヾ(❀╹◡╹)ﾉ~

Any manga with stuff like mind games? Like a super naive mc who trusts everyone but finally realizes the truth and finally snaps and becomes twisted or evil.
