So

I wouldn’t say he got groomed tho, Yullur did nothing wrong???? He too find it awkward and doesn’t want Saya’s affection (so far at least)

I dont think groomed is the correct word in this situations, even Yullur is rejecting Saya affection. Its mainly Saya who wants Yullur, all Yullur did was be present in his life.

So what was the kissing flash back?

The few pages before was definitely a flashback but the next few pages were him dreaming about that kiss

Actually wait a minute, im tripping maybe....

You feel me????

He flat out rejected him and the kiss thing was a dream, even if it was a dream about the past, things can alter what happened with desire in dreams.

No no it was definitely a flashback turning into a dream. You can see he’s older by the end of it, looking like how he looks now. It was his own desire shifting the memory, not a real flashback (and that’s why he wake up startled immediately after)
