I am an older sister and have a younger sister. She had a boyfriend before me. ( I still am single and she has had a relationship plus break up and get back together and now marriage talk since 5 years). In the beginning she was hiding it from us all, even me her sister. I was concerned when I learned about it, but when my mom learned of it and got angry about my sisters hush behaviour like some criminal and hiding and doing things behind her back as a minor especially, my instinct was to defend my sister and not try to be some possessive freakish sister. There is a difference between where being siblings and being protective starts and than goes overboard into the "not love anymore, but some projected ego shit". Throughout my different periods of age, where being the "older one" was experienced my me differently in correlation to my sisters mental age and stuff ( I was an adult, when she had puberty etc.), I learned that usually, when I tried to force her into believing my opinion that was meant "for her good" was actually my ego talking. Sure, I really meant it for her good and out of concern, but the moment I begin to cross her line as an individual with her own path, is when I stop being "a loving older sister" but become a selfish asshole. I have no business to tell her what to do with her own body, what to do with her own life and with her own feelings and who she directs them at. She is her own person with her own path to walk, with pains and crisis and troubles that are entirely her own and who I may never know of. I have to respect her, because I love her, as her own person. She is not a mentally ill person or in any way mentally handicapped, that she needs me as her forever legal guardian who decides over every step for her. So a sibling being like this actually disgusts me every time. Because only an older sibling can understand why they are doing that and an older sibling that overcame their ego will see how toxic their behaviour is. It is not ever cute when a sibling acts like this, but just disgusting, especially when they play it off which is to me gaslighting. Parents also have no business to tell their child how to live for example. So how could a sibling do that? IF they do, then no matter how bubbly the family looks, it is a dysfunctional/toxic family that knows how to hide all that poison thanks to successful gaslighting.

Yeah I totally get it girl. I’m starting to see how he is invading her private life and especially love life since she is turning 18 which is the mature age to be responsible for yourself. Honestly, I remember being super over protective of my younger sister she completely cut me off for a few years.
with each new chapter. "Do you guys need to stand that close to each other?" What the fuck, dude, they're under a frickin umbrella. And that "Stay away from my sister"?! How about thanking P'Chen for being there to keep her out of the rain instead of being such an over-the-top fucking sis-con?
