Some people are scared to love again but hey, the experience and memories you shared with is really worth it. And use it as a key to move on, to learn and be the better version of yourself. Love is everywhere, not just for one person. It also not a curse or a weakness, its a gift you can give for other people or for yourself. If you think that Mincheol is a waste of time, I do not think so... FL felt safe when she was struggling in her teen days because of that guy. For her he was her comfort person and I'm satisfied to see him make her happy. He 'was' useful, but I guess thats all he can do. It's sad but people change, as well as their feelings and also you can't force someone to stay put.
I know its a stupid and selfish idea to cheat on your lover to see their jealous reaction and gain entertainment and satisfaction. Its so, so wrong. If you feel they are less expressive, its just that, the person is tired, or they don't have a reason to feel emotions like happiness.
But hey, I love FL mentality, she is strong and I agree with her. Be happy my gurl!
