Kokoro O Korosu Houhou
Ch 17.6 Literally loved this... i havent completed this when it was still updating but now i finally finished it wholesome. Haruki x Hikaru Stepbrothers... this relationship was inevitable since the beginning. When Hikaru felt disgust of women(or those who tried to molest him and caused him trauma of disgust) he met Haruki and was saved by his presence. Those feelings meant nothing. Then he later knew he was goning to be his step brother. From here the story starts... Haruki works in a law firm.. hired by his senpai Hanabusa .. hikaru was 13 when he started getting attached with Haruki. Haruki had no idea. When hikaru was being molested by his teacher... he came to haruki's house and kissed him.. forced to touch him. Haruku felt weird. Haruki wanted to deny that..but hikaru still demanded more. He made him have him suck him and recorded a video. Later when haruku had enough, he tried to stop him instead was being threatened by the video. Haruki had no choice. But it was haruki who accepted it first.
