timeline: tsukasa just found out his dad collapsed, meaning after graduation he'll need to go. (hence the propsal)

rui: so, what are you going to do, makino?
tsukushi: what am i... going to do? well.. it's not like he's not going to come back! just like before.. if we want to see each other, we can, right?

all stares and quiet..

tsukasa: i think i won't be back for four years.
tsukushi: four years?! what is this? olympics?
