So shruo has the ability to summon kou here -first chapter But kou already in his earlier timespan was in love n didn't get together this kiku/shruo grandpa And the grandma was also suffered from some disease so needed a companion to help him in daily basis ( which was kou) but both fell in love, the grandpa didn't want to waste kou's life on him (like he was dying? so never confessed) then kou got adopted into the family, kou wanted to repay the thankfulness participated instead of the grandpa in the war, but then during war grandpa got a message kou died maybe without the body returned back grandpa refused to believe so n hence became self distanced from others n waited for kou to return n the grandpa's dying wish is to meet/ love kou n not kou be left alone dying in war in grandpa’s place While there was a letter kou died to the grandpa but actually kou's aeroplane was just lost? ( first chapter so I believe they couldn’t retrieve kou’s body) so he was stuck somewhere in time...n wished to meet the grandpa too So when the shruo used that old plane he got summoned n that's this story starting But through out this entire time line in the past the grandpa is still waiting for kou So kou once again self sacrifices to try to meet the grandpa in his time line by going back to past time to meet his lover/ shruo’s grandpa and n also fulfill his dying wish of the ashes to be scattered in ocean
Kou said let's live together to shruo so after some time shruo will fly that plane again later to summon kou once again n thus shruo will be reunited with kou So my doubt is here Whats up with shruo uncle back story, I didn't quite grasp it, like the grandpa was hostility to others so shruo’s parents double suicided in abroad(?)[ I assume it’s cos the parents got depressed by grandpa too so kou going back in time will probably fix grandpa’s relations with shruo’s parents so preventing them suicide too] And thus there is a change in family photo in last chapte, instead of just grandparents and shrou we can now see shruo’s parents too and since kou successfully time traveled back to reunite with shruo he’s not in that photo!!!!! I don’t accept any other conclusions
