It didn't have a sad ending, but I don't know why it gives me mixed feeling,(Uke) he travel back in time for the( idol) he always love, but that (Idol )is not the (same), (Idol) he was (same's) friend who type of stole the(same's) position or something, (shame) fallen love with (uke),but (uke) still like that (Idol) later (uke) & (shame )like each other and love each other. But when the time comes (UKe)travel back in her original time. They promise each other to meet, but unfortunately(uke) forgot the (same )and after that( shame) try very hard and then (uke) remember again . After that they leave happily Ever After .it actually good Manga and even the (idol )means (shame) friend who STOL his position, is not that much of a bad guy. but for me it's give me a little bit heart accahs. But you know everyone have their own preference so it might shoot your taste you can give it a try it's a good Manga after all (=・ω・=)
