You were sitting comfortably on your desk in class, chatting with the boys

The girls were chatting among themselves and you heard a few girls talking about Runa, who was a bit curvy

"I'm sure if you had a boyfriend, he wouldn't even be able to let you sit on his lap because of your weight!"

you got angry at the girls because Runa was a girl who was sensitive about her weight. You took Runa in your arms and grumbled

"Don't talk nonsense"
