Reject A Love Confession

I have a friend I'm going to name him Aiko. So me and aiko been friend for 2 years(but it's feel like 5 days). Well, I can tell that he is nice. We goin to school together, have lunch together and even going home together. One day(lol why am I so dramatic) I can't go to school because of sick, yeah I'm staying home. I ask my mom if aiko come to my house of not. My mom said he did, he ask my mom why I didn't go to school ofc my mom said "Yoshiko sick" (not my real name) and he go to school alone. (I don't really remember how many days I got sick, I just gonna say 2 days) i was about to go school I see aiko waiting for me(we Always go to school riding a bike, it's was so funnn). He park the bike and go inside the school. When we about to go to the class I hear someone said "BABEEE" I look and I see she coming to our direction. The first think that make my heart hurt so much, she hug aiko and aiko hug her back. Aiko look at me and said "this is my girlfriend". I'm sorry I can't.
