Fight Between Former Lovers

The school bell rang, a signal that our class ended. I shrugged to my classmates who are making a fuss over arranging their things. I immediately left the room after I finished fixing my things. As I exited the gate school, I suddenly felt having a hard time breathing and I noticed that my vision was a bit wavy, despite that I continue to walk. When my normal breathing came back, I sighed in relieve. I was about to continue walking when I heard noise behind my back, I turned my back for a seconds to look what's the commotion but they are all waving their hands directly telling me to come back but I don't know what they are referring to until I heard a horn from a big truck that's about to hit me. Before I could process everything and before the truck hit me, I immediately lost consciousness. And I didn't know that, that would be the start of all of this.
