my dear readers, sorry that I keep going on about 溏心风暴, i really got my facts wrong. okay the general idea is still there, just the setting's a bit wrong. watch it for yourself. everything is damn clear in this 10mins video clip. can't believe I actually searched for it!
in it you'll see girl B apologizing to girl A. (1:48)
so it's like LF actually took up scuba diving courses cos of girl A. (1:05) then while on a trip he picked up a really pretty seashell for her. wanted to give it to her but yea... car accident.
hence the "i actually wanted to give you two things, but I guess I can only give you one now.."
