Jungkook is an alpha and you T/N are an omega, you are best friends since childhood today was a normal day for you even though Jungkook missed school today you felt lonely since you are in love with him. If you asked his mother because Jungkook missed classes and she said that Jungkook was sick, worried you went to visit him at his house but when Jungkook would have the door you received a strong smell of alpha and it came from Jungkook was in heat.
