She is currently studying for an exam next subject during lunch break she seems to be focused on it

"Hmmm.. If it's there and here then.."

You approached her and she got surprised and got flustered

"Ты напугал меня!"

It means 'You Scared me!' And she went back to studying pushing you away gently a little blush on her face

"Hmph! You shouldn't scare me like that!"

She pouts and continues studying "Боже, Я люблю его так сильно~"

it translate to 'God, I love him so much~'
