i can't believe i'm defending this manga... but it's not lol believe or not humans are pretty contradictory. and not to mention it's incest. they're not supposed to be together or want each other. so big sis convinces herself she can pass him up to others in no time. but inside she still feels like she lost. it's normal. no one is honest all the time, especially with a secret like that@AnonMan88 I get you, but it seems like such "fictional character logic" that it's hard to sympathize or believe. She loves him and wants him to herself, so she's going to hook him up with other women? Righto... Who could have foreseen her suffering?
