I honestly don't have a problem with this, if I like a story and the lore gets expanded by the original creator, by all means please do, it'll be fun to catch glimpses of the characters that I knew from the earlier works and know what they've been up since then + at least the author's being experimental with it by trying to explore different pairing instead of being lazy and just repeating the same plots over and over or dragging the main story to the next ice age just coz she knows there's a fanbase who'll eat whatever she throws at it. Don't get me wrong it's not a masterpiece at all and the previous stories are actually problematic, but it was a good read, so I like seeing that there's actually more to it.
but I also can't help seeing the ML looking like the love-child of his aunt and that other Alpha friend in the sequel story LMAO, specially that last panel of him panting, yeah for sure that boy's the seme in this one (I know, I know the characters are underage now but it's fiction and we'd most likely see them grow eventually, plus it's Fargo cmon it'll be an even bigger plot twist if this actually continue to be shounen ai to the very end, IF it continues to have a regular run and not a short one like the sequel)
On another note, what was the author cooking by dragging back the maternal grandma to this plot? That character was and is a POS, her reconciliation attempt is not enough for the way she treated and left the MC's mom in the main story, and now she's getting chummy with the husband and son? should've ended her participation in the main story as is.
Also to the uploader who bulk released the chapters in one day, thank you so much for giving sustenance to plebs like me hahah.
