*SPOILER* Apparently Chad was so nervous for the 日付 that he drank water continuously during the date. So when Chad was like: "Sonny, can I ask あなた something?", Sonny went very "hot" and did one of those "popular girl" hair flips while going "Yes, Chad?", startling him, and he starts puking on Sonny..... Watch the part 2 in the vids.
Obviously because its there first 日付 they are both really nervous, so they keep on talking to their selfs and Chad can't stop drinking water and he says to himself "Tell her that she makes あなた nervous, she'll understand." so he says to Sonny, "Sonny, I need to tell あなた something," Which Sonny 返信 with (in a 'hot' way) "Yes, Chad?". Chad becomes even もっと見る nervous and vomits on Sonny, Chad quickly leaves because of what had just happened, Sonny says to herself "Oh my gosh, I can't believe he just did that! Why am I saying this to myself!" Then she shouts out "Oh my gosh, I can't believe あなた just did that!"
