In the first copy, the house that the group are living in puts strong negative emotions in people that build up over time, at least that's my understanding from MTL. Some characters experienced anger/wrath, others experienced envy, and we see that MC has I think depression or fear or sadness? I think that's what lead him to cry so much but I may be wrong.

Ji Yu: Honestly he terrifies me. Truly suits being the king of hell. He's the god that wants to see mankind descend into madness and will do what he can to aid them in their descent. He's a master manipulator and is able to control his speech, actions, and facial expressions so well that he's able to convince you that he isn't bad and is gentle and kind even though you know he's evil. Both MC and I have been fooled by him twice even though I did eventually catch on but still... I will admit though I love Xiao Jiyu, shows up in Rose Castle (?) scenario, so much and I will do anything for this child.

Si Kong: I actually really liked Si Kong since the beginning. I'm not sure which god he is but he's one of the ones that stand on the side of humans. He tries to help them in the ways he can, despite the multiple restrictions there are on what he can do. He's the most trustworthy of the gods and we can see that Wen Qing also knows the nature of Si Kong and thus feels safe and relieved when Si Kong is around.

Yu Xing: I never know what to expect from Yu Xing. He's a god that mainly focuses on lust and love and one that just wants to play games with humans. This makes him really unpredictable because you never know how he's going to mess with the situation. We can see from the first arc that he enjoyed messing with the players' heads and making them doubt him and each other. He could help them clear the task but he'd rather they stay in there so that his fun doesn't end. But then we see him help Wen Qing as well with solving the task so he's not totally evil but he's not good either? Like I said before he just wants to play games. Although of the gods he is the most pe*verted one and sexually harasses the MC a lot.

Zhou Zhou: THE SCARIEST HUMAN MALE LEAD. I swear Zhou Zhou is so unhinged and creepy that I literally cannot with him. He is unabashed in his twisted like for Wen Qing and wants him no matter how Wen Qing feels about it. He seems to enjoy playing around with MC and seeing him on edge... Sometimes I wonder how much of Zhou Zhou that we see through most of the novel is how he really is, and how much was him getting twisted by the first arc...

Bai Tong: Finally a decent ML is introduced! Him and Wen Qing meet when Wen Qing goes to the player living world and then again in the second copy. He's the first person that likes the MC without being super r*pey and forceful to him. He doesn't make unwanted advances and he doesn't sexually harass the MC. He protects him and helps him through the copy. He respects the boundaries of the MC and is seen as a responsible teammate that the MC can trust. I haven't gotten to where he reveals his feelings and I don't have hope that it'll be reciprocated but Bai Tong is at least a light in this cruel pile of MLs.

Oz: Another insane ML, almost on the level of Zhou Zhou. He's also forceful and harasses Wen Qing, but seeing the interactions of him later on compared with Zhou Zhou, he's not as bad kind of respects the MC's boundaries a little more?

Ye Ye: Ye Ye is kinda like a little tsundere who develops a school boy crush on Wen Qing. He thought badly of MC before because he thought Wen Qing seduced Bai Tong and Oz to carry him through a scenario, but he learns that's not the case and ends up becoming friends with the MC. He's one of the decent MLs and I root for you Ye Ye even though I'm almost positive you aren't the real ML. We really see MC's character change when he stands up against Ye Ye when they first meet which is a refreshing change for him.

Xing Ze: Honestly, one of my favourites. Starts off as an NPC in one of the scenarios that is set up to be Wen Qing's friend and is a police officer that is solving a case with MC's help. He takes care of the MC and protects him and doesn't take advantage of him even after figuring out that he likes him and MC is often vulnerable around him. We can see that MC really trusts Xing Ze and associates him with safety. He probably won't be end ML but I really wish it...

Jiang Yan: Our resident crossdresser and flirt. He comes on strong to the MC and flirts all the time but I'm pretty sure he has never been violent and forceful to Wen Qing. They did make out once but that was so Wen Qing wouldn't get caught by Oz and Zhou Zhou. Overall he's been really helpful towards the MC and despite how flirty and frivolous he may seem, he's helped the MC since they met and goes out of his way to protect him, which can be seen when he comes back after scouting the whereabouts of Zhou Zhou, Oz, and Ji Junfeng during the Going Home arc. I also really root for him although it probably won't be him in the end...

Ji Junfeng: At least he's dedicated... Literally turned from NPC to player just to be with Wen Qing which is kinda cute if you can forget he's like part vine monster that wants to lock up MC for himself???

It's actually 001! The system of Wen Qing! We can see that 001 has a sentience that other systems don't have and he helps and is there for the MC when no one else can be. We see hints throughout the story that there's more to 001 than just a regular system and that he may gain a body in the future??? I'm not really sure, this is just my guess but I love 001 so I'm rooting for you too!

the creator god and also Wei Qing's irl roommate. Everyone is sort of a fragment of him but they don't actually merge. That's why he's so attractive to them because they're influenced by ML.

It's kind of bittersweet. He gets to have a final moment with all of them but I'm pretty sure they're their own entity.

But in the end, they were all fragments of the endgame MC which does explain why so many guys like him out of nowhere. It's because it's the SAME PERSON. Feels like a cop-out though which is often seen in Chinese danmei (many guys turn out to be one person). If you're going to make a harem, stick to it! If you're looking for a REAL HAREM danmei, read Bird Dude Nie Bufan.
