One thirsty dude:
1. うわ可愛い - Uwa~ cute
2. えちょお姉さんお姉さん - hey older sister (I'm aware えちょ may be a slang word idk what for tho)
3. 暇ですか - are you free?
4. 暇じゃない?ちょっとちょ一緒に - I don't have that much free time. let's do a little together.
5. 行こうよねちょっとお願いお願い - let's go, please
6. ちょっとだけだから - because I only have a little (time?)
Tired of translating but the other boy basically is like what the hell are you looking at while the thirsty boy is like eh eh in disbelief and then he says 怖かったー ( I was scared) and thirsty boy is like えどういうこと (what do you mean)
