Uke could not pull it off from the start. He may have pep talked himself and trained his body to fully immerse in the mission, but his will only went quarter a pounder of an ass cheek. He none have the experience, capability, nor iniquitous character to execute. He's a bruised spring flower of fiery eyes with heart that flutters in the wind. While Seme is a monster mutated to digest toxic swamp sludge he was thrown in to drown. His reflexes and instincts to survive precedes any youthful innocence clinging onto humanity. But for a moment in arid desolation, two drops of morning dew touched...
If One Day are memories, where are they now, how long has time passed, and are they still together. Or is it just a youthful fantasy of a character, and in this story of imaginations, is that person real. And just like that, a blip a pop, a magical glitter appears, disappears.
Chapters 22 - 50 are actually the present.
Jian Yi came back after 3 years of being gone and is living with Zhan Xi who is now in college (Jian Yi has to make up high school). While there's tension between them they seem to have made up. Also some special chapters (like the Christmas Special in Chapter 224) also take place during the present. So you see both couples are still together.
The other chapters are flashbacks taking place during their third year of middle school, right before Jian Yi disappears.
They all know each other irl. Doha already like Bada. But maybe Doha sick, so created and uploaded himself in a game. When he died or his body is beyond function, he then invited them all to connect to his virtual world "Come spend time with me as last farewell." But the group didn't know they'd fall into the program. Irl maybe Doha rich and have personnel attend to keep the group's bodies alive. That way Doha can continue his time with Bada.
Plot twist. What if to unlock the true ending, Bada had chose to stay with Doha. After a period of their mutual bliss, Doha could grant their freedom. Maybe his last wish was to feel that peaceful assurance from Bada.
