This is really living rent-free in my head right now. I'm overthinking for her. Thinking how long has it actually been since he began having secret trysts with FL's sister? Months? Years?
Meeting up at dawn and making out together, without FL ever knowing (maybe they did even worse than kissing, hopefully not because he's only in highschool while she's an adult).
How will FL trust that if ever FL and ML do get in a relationship together, he's not still having secret meet ups with the sister behind her back?
Even though ML and FL weren't together when he kissed the older sister, that level of secrecy from your best friend is still a betrayal.
Unrequited love or not, doing that to your friend's sibling behind their back can ruin a friendship! I thought he was desperate to protect their friendship??
Sometimes I don't comment, thinking that some people might take the comment the wrong way, but then today I just saw an entire comment section in yt get offended because the person in the video called vanilla ice cream "plain".
So... I learned that no matter what you say, no matter how non-issue it is, it will be escalated worse than you ever intended.
(Not to say you should just comment everything from your head, but just know that even if you already took measures to try not to hurt someone with your take on something, someone out there is still going to see that as a personal offense).
Aww ML and FL is kind of good together after all. The only reason for their bad parts is because of external things, but if they were free to date as they pleased, they'd be more open and loving.
