While streaming, a commenter revealed the location of the ML during a ranked game when they were the last 2 and MC didn't take advantage of it, instead, he told ML "This wasn't a fair hunt, therefore, I'll give you two minutes to change positions. The next time we meet, one of us dies."

Ginger??? This is a new one for sure. Spicy and healing~

MC wants ML to call him gege but ML refuses until MC defeats him.

sticks with his plan of removing his gland until the end, becoming a beta even after falling in love with ML.

getting bonded to an alpha (ML's brother) behind his beta lover's back. He didn't even have the decency to break up with the beta first but is continuously depicted as a victim of circumstance and never faces the consequences of his actions, just goes off to live a happy life with his new alpha.

The first one where MC have the operation. I like this ending more as both MC and ML were free. Though I did feel sorry that ML can no longer smell MC. They retired, ML went to the army as he wanted, and MC finally let go of his shackles (the mentality of being a soldier in previous life and the constraint of his omega gender). MC followed ML in the army as a relative. ML as a soldier have to explore new planets (cause there's no external wars) and MC goes around to do stream sports. I'm happy with them here.

The second extra is where MC didn't do the operation and start omega movement groups. As a result, when ML retired, he didn't go into the army and followed MC as a camera man because MC needed him. I feel like he still didn't fully mark MC here as MC regularly needed him. Although I did like MC not to have the operation so that ML can still smell him, I don't like this ending. MC still couldn't let go of his 'sacrificing' mentality and as a result, ML had to sacrifice as well. In here, MC confessed his background to ML and ML felt that MC was morally kidnapped to be sacrificed so ML went to fight with his 'mother'. I laughed that his mom was so confused and the father had to go in rescue with a ruler ahahahaha.

In the third extra, ML while asleep, transmigrated into an 11-yrs old picked up by the MC in the previous world. He cling to the MC and MC had no choice but to raise him. Dude I really feel sorry for this ML, he had to very ferocious as the world in the apocalypse is very open, he had to be shameless and cling to the MC no matter what as the chances of them being separated is high and MC was constantly being hit on and ML is still a kid. It's funny how ML still carries his morals from the previous world that he sometimes missed how morally crooked people here. ML worries about being raised by MC while MC just asked him why didn't he jumped him earlier.

ML really guard MC hard and he eventually got MC stuck with him. The reason I said this is probably a prologue kind of extra was because in the main story, MC indeed have dreams of a man similar to ML in the main timeline (there are times in the main timeline that he sorted out his feelings for ML after dreaming of a man. He thought it's just wet dreams). I kinda just wondered how MC forgot all of this and think he's still single when they're literally together for like 10-15yrs and died together. Also, I feel like this is the past of the federation rather than another world. The game maps are too much like the destroyed apocalypse world. Also it's mutation type of apocalypse.

Before the ending, the leads found a place with green plants that didn't mutate. The place made humans cause mutations though despite the immunity injected to them. ML developed some fever similar to suspective period of alphas as it made him very h0rny and only subside after doing the deed with MC. The two died before there's any results and the author didn't really explore this anymore. Though I do believe that the world eventually had humans mutate into ABOs.

he usually avoids using his pheromones when confronting other people in case the MC gets affected from the sidelines

defeating them in battles, in the full-dive world and in reality as an omega too!
