a lil spoiler ...
oh sorry for the misunderstanding
that's not what i mean, i mean the system offers him a skill that will be useful in the future. Meaning it knows what will happen and hints at it by giving him seemingly useless skills. For example, Moondae thought having the skill to turn on and off your tear ducts is pretty useless compared to other skills he already have but then this thing happens and he ends up crying on stage and he realized the system may have been hinting on this future event where he can use this skill (to "turn off" his tears at this time to avoid getting embarrassed.
But for me, I'm glad he didn't have the skill because that moment was very precious, to him and to his fans. And I like that him crying when he didn't cry at all at the awards and sht like that emphasizes the preciousness of this stage. Ykwim?
I'm not articulate but hopefully u get it

It's that skill right? The one about not holding any tears or something like that, because after this, Moondae will cry in other events
