My Fucked Up Life

MC is living with his family, planning on moving out. His mother, though she loves him, don't want her only son to move away from her. Although, it looks like a normal motherly affection, there could be a hidden taboo desire behind that. MC's big sister, always had a crush on him but she is too shy/scared to act on it. And then there is a lingering threat of NTR (Avoidable) around MC. Help MC on his journey of fulfilling his dream and possibly help him get a girl or a harem
