MC and ML met and fell in love as balls of primordial energy before the universe as we know it even existed. By the time MC and ML took human form, they were already several millennia old. MC's true form does have a teenager's appearance, but if you read historical danmei novels or even half the popular Seven Seas danmei xianxia danmei titles where most MCs are around 16-18 years old, I don't think this will be much of an issue. There was a misunderstanding where ML thought he had misread MC's intentions, and MC didn't actually think of him as a lover but as a family member instead. He tried to bury his feelings and did not pursue MC at all, only to find out later that MC did feel the same this whole time and was just unable to communicate properly.

The MC and ML had actually met a lot earlier but the MC died so ML had to go back in time and do all sorts of things so that they can be together. We get to see plotpoints or backstories told from the MC's POV from the ML's POV.

ML and MC are a heaven made couple who were together since chaos age as qi!!!! They were the very first gods in the world.... they also got together but ML had to go to a competition regarding being the main god at the threat of mc's safety... but at the final match ML ran away because he sensed that MC was in danger which in fact the gods of that world getting obligated because the son of the fate of that world had died.... MC froze time at the price of his own godhead. It was said in the story that once a god falls even the soul would also be gone! ML came back and found that MC was getting melted in the snow. He was desperate and then saw mc's soul still persisting to remain because he had an obsession of wanting to see ML for the last time. Then ML split his godhead and saved MC. Both fell back in the cycle of birth and finally meet each other again as snow god and evil god in the modern era!!!!!

it also has side couple who has their own story. I haven't read it though. But the ML of that story helped ML of this story. Since I'm giving you spoilers then let me tell you he is the main lord god you will find throughout the novel.

QT, Transmigration, systems, rebirth, novel in novel, zombies, apocalypses, time travelling, chosen one (I don’t know the translation for this), multiple worlds, multiple Gods and abilities. (The QT, transmigration, rebirth, chosen one thing and systems don’t happen on the MC and ML, they just happen in the novel as side? Events)

the author really just went all out, author just threw in the multiple world plot line and systems straight away. It's not new of course but dang I wasn't expecting it. So in this world, the world god (AKA the main characters) are aware of the concept of multiple worlds and even the existence of a "main god" that is higher level and overseas these multiple worlds. There are also "systems" and "rogue systems". Proper systems are sent to help save worlds on the verge of collapse but rogue systems are unwanted and can harm a world. So MC (the snow god), actually has god work to do getting rid of these rogue systems possessing people. Like there's actually this kind of plot line that I wasn't expecting? I was expecting maybe ancient xianxia type of story haha. It's a pleasant surprise though. ML on the other hand is very lazy and didn't care about it much (at first). I like the messaging system they even have to chat with other gods in other worlds.

the system and host side pair that was really cute. Glad to see their happy ending.
