Later I realized, I truly no longer love you, and it’s very difficult to fall back in love again.

That feeling is not the disappointment after being betrayed, not the hatred after being hurt, but rather calm and everyday; I calmly feel indifferent to our past, and also calmly admit that you are just an ordinary person.
I even seriously considered your experiences, your personality, your abilities, your growing environment, and your cognitive makeup, and in the end, I think it’s normal and understandable that you can do these things.
Actually, fate is quite good, allowing people who should be strangers to become strangers again.
Your appearance, hobbies, and even your style of dressing haven’t changed, but I no longer have the desire to see you at a glance in the crowd.
