Abcjwjdjwhss you're so right, it never really resolves until the final chapter before the epilogue

I love how the over-arching theme of the story is the love between Yhyj, brotherly or otherwise

It fits really well that the main story ends with an "I love you"

A tiny piece of his memory regarding that watch he was meant to give Yoojin over Hyunjae gets lost. This might seem like a minor memory to lose however it plays a massive role in Yoojin's emotional state within basically the upcoming 150+ chapters, ending up with a massive panic attack on Yoojin's part due to failing in recovering the memory after a certain fight and reunion.

From this arc onwards, Yoojin and Yoohyun will not only have a more strained and co-dependent relationship, but both of their mental states will be going downhill up until a soft resolution in chapters 350+

Ilya really isn't controlled by the system. In chapters 16 - 17 he basically proves to Jerry that his love for him is real. Ilya can see the system pop-ups at that time and he sees the "favorability" scores of himself and Karyan.

When Jerry tells him that that's the reason Ilya doesn't love him for real, Ilya just messes with the system and reduces his favorability towards Jerry to 0 but remains saying that he likes Jerry
