Honestly this was so cute wow Maybe not a 5 star complicated plot or anything but it made me happy so why not lol And ch3 of shuuden ni wa kaeshimasu is the first chapter, this one shot is the second chapter
Cute story of two highschool girls...the senior Seto Asaki and her junior Akuyama Tsune. Both have been going out with each other and start develping feeling towards one's another. With graduation approaching, there is not much chance left to be together. Duringthis mall shopping, both confessed their love and get a sense of stillness eventhough they will be separated when Asaki goes away and attends the University. What will their future holds? Cute drawing.
I don't know why it says oneshot and it's only one chapter... it's pretty clear that the start of this "oneshot" seems to expect you to already know some things. Turns out that this "oneshot" is the second chapter to the other manga with the same name http://www.mangago.me/read-manga/from_aiu_station_on_the_hiragana_line/ which is marked as ongoing... good things to look forward to :)
