Secret got out? (given)

then why?

uenoyama was walking to school half asleep when he  felt like someone was watching him. He looked behind him and saw ayano.
"Hey do you need something"
"O-oh" she said, startled
"I- can you meet me on the rooftop at lunch"
"Yeah but why?"
"Just come"

While Ueki and itaya were playing basketball. Ue asked "hey what does it mean when a someone asks you you meet on the rooftop.
Ueki and itaya's mouths dropped open
Y-your joking right?" Exclaimed the both of them.
"No why would i be"
Ueki and itaya froze in place.
"its probably a confession" exclaimed ueki
"which girl which girl" asked itaya
"kasai-san" said uenoyama
Ueki and itaya froze, suddenly they both walked up to him and patted him on the shoulder, "WHY ARE YOU SO DAMN POPULAR"
"EHHH??"

(Though does kasai really like me in that way? If she does confess then what? Well i doubt shell actually do it so I guess i wont worry about it too much)

*bell ring*

Mafuyu came to uenoyama's classroom to ask if they could practice. "ahh im gonna do something real quick" explained uenoyama.

Itaya said "heyy mafuyu come with us real quick"
"huh? Ok"

Itaya forced ueki to come along too and the three of them followed uenoyama to the rooftop.
(rooftop? Whats happening here?) thought mafuyu.

"hey uenoyama... I need to ask you something"
Mafuyu was shocked to see kasai waiting their
Closest to the door was mafuyu then behind was itaya followed by ueki.
"hm yeah what is it?" replied uenoyama.
"are you in love with someone?"
"huh? W-well"
"are you dating someone"
"what are you-"
"...."
Kasai had an intense look on her face.
"You....your going out with sato arent you?"
