Cairo (your boyfriend)

You and Kairo have been dating for a year like a perfect couple, and you go to the same school at Region High School, even though you and Kairo are already dating, your boyfriend has a childhood friend named Sheila. Since Sheila's arrival, everything has changed, Kairo often spends time with Sheila rather than with you, likewise Sheila, she deliberately always blames you and pretends to be weak in front of Kairo because she has always liked Kairo, and easily Kairo believes Sheila's words more and blames you instead.
