This is the reason why I avoid reading harem ಠ︵ಠ and to make this worse is when they pull the incest part. At first, I feel sorry for the mc bc someone tried to kill and sa her (which is her own brother yak) but the end clearly tell that she also likes her brother for a long time and just as possessive as them. For her true brother, i don't like how he became the one who tried to kill her like what the fuck? Just kill the triplets instead of scaring your sister like are you dumb? And I really feel like he became the killer just because the creator wants to clean the triplets name (of course I'm not buying that). Overall, I just read this to past time and I didn't expect anything bc I already read the other comments.
