As Kurt ram through the events of the [MEMORY FRAGMENT], he understood where his older version went wrong and where he went right, but what shocked him more was how he couldn't make a good use of everything he remembered from what seemed to be his previous life.
It seemed like his older version didn't have a good memory at all, or it was just the system toying with the way he should recall past events and use them to his favor.
The younger Kurt wasn't a cold thinker, but he still had a lot of so-called 'useless' knowledge that he acquired from webnovels and videogames. Which allowed him to think outside the box when it came to the older Kurt's memories.
The only problem was that, if everything older Kurt told him was true, that version of the world didn't bear much useful knowledge for younger Kurt to thrive in his own world.
