"Irradiation" is a word in ENGLISH

What should I call you? A friend, a stranger, or a lover? I remember the day you laid your eyes on me the first time. There was just something unwavering about that moment. It wasn’t peaceful or absolute. It was definite. Something that was bound to happen. It was like as if our souls were waiting for us to collide. And oh we did! We collided like meteors, giving this universe a spectacular view. From my 2 am thought that used to keep me up at night, you soon became my 2 am call. From an almost stranger to my skin, you became a part of me. But just like every collision, ours also had to end in destruction. The 2 am call soon became a 2 am thought. The thought still keeps me up at night, but not for the same reasons. From strangers to lovers and lovers to strangers again, our journey hasn’t been ordinary. Someone asked me about you today and for a moment, I didn’t know what to call you. Who are you to me now? A friend – no. Definitely not a lover. I guess, you and I – we are just strangers with memories.
