I don't get why people think that this is "fast paced". If it's the fact that they kissed after they became officially a couple, that really doesn't make sense... I mean... did you people never DATE? I realize that the majority of manga story lines use the "both people are so shy and reserved that they can barely even think of holding hands until they've been in a committed relationship for months" formula, but the majority of relationships that I've been in started either with asking her out on a date or meeting at a party, but either way, before we were "officially a couple" there was usually at least one make-out session, followed by the awkward, "Yeah... so... I guess we're together now, eh?" discussion. (Only one time with the... "ummm... I need to make a phone call before that can be official... / OOOPS I totally screwed up" caveat. - yeah, I was that jerk once in my life... it happens. Happened to me as well.)
Maybe kids today ARE that different?
