There are some light dom/sub elements + gege kink, touched starved, separation anxiety.

light PTSD, talk of suicide/self-harm, talk of death/dying.

videocall....

Chp 55
Even though YZ was the first one to say He liked him (SY) but it was not one sided at all.
SY is not a typical tsundre ML, he told Le Le honestly about his feelings that He (SY) had liked him for long long time right after YZ's confession. Even though ML has cat like personality but he express his feelings to the MC.

the complexity of their relationship. Both MC and ML are raised as brothers and everyone around them consider them as such. But they fell in love with each-other and are afraid of disappointing their parents mainly.

when they came out to their parents and the draft letter by the ML. The letter is so touching. It is around 90th chapter

ML has serious 'bullying during sex' kink not that the MC minds, his speech is cold even during sex

with the ML ofc being in unrequited love for years

they get together, it's all MC initiative, MC confessing, and MC pushing for the relationship. ML in fact was very scared that he affected MC way of thinking as ML is all he knows, so he makes sure to never influence MCs thinking and leave it up to him. This addressed any possible power imbalances that could've come from their "older bro/younger bro" relationship. It was handled well

SEX. s*x SCENES. This author does great s*x scenes that feel tempting and nose bleed inducing without seeming vulgar or tasteless. Because of their dynamic, its lowkey SM play going on (not bondage, more humiliation kink and power play) which I surprisingly enjoyed as it fit their personalities. MC is very obedient in bed and ML makes his demands based on MC pleasure. Really sexy! Trust me, you'll enjoy these scenes. Theres a good amount of them too not like alot alot, but you'll be well satisfied lol.

The ending is HE and if your like me theres no weird time skips or forced separation to make the parents accept them. At first the parents dislike the fact that they were raised together (not nessecary the gay part) but they both stand up for their love, esp the MC who in this case had more reason to feel guilty (he was raised by ML parents and felt indebted to them but technically ended up snatching their son) but he stuck by ML and they never broke up.

There was a chapter that ML's mother found out about the letter ML wrote when he was young. It was so touching when ML revise the letter 11 times to give to the future MC's lover. - from this, u can already see how much ML loves him, to try to not show his love for MC and try to be a proper older brother.
Tbh, most Chinese families are still quite conservative and are respectful to our elders currently, so it's more difficult to express a BL's relationship, especially when u are raised in a family together. So, for their parents to give their approval makes it even more touching.

in Chp96, the kiss makes by MC & ML under the Christmas tree was exposed in the school, but they handled it by calling the police and find evidence about Wang Zhi.
This exposure resulted in them coming out of the closet. Yet, many ppl accepted it.

Though it's written in his character setting that MC is a sickly character, he's actually pretty stubborn and brave when the situation calls for it. He's also a fast and calm thinker. On the other hand, ML is also written as a cold, unfeeling character, but he's actually holding in a lot of his feelings inside. He actually takes others feelings into account and it's not until the end that I realize how noble his career pursuits are. Which brings me to the next point.

BIG SPOILER YOU'VE BEEN WARNED

Near the end, an accident occurs at the site of where the ML and his group went on field work for their course. MC goes to find him and you'd see here how he overcomes a lot of his past trauma coming from the death of his loved ones. It's such a shoddy summary and I don't want to spoil all the deets, but hear me out. MC did a lot of things outside of his ability. Like both physical and emotional ability. At that point he was just so so brave and decisive I couldn't help crying my eyes out.

On ML's side, you'd see plenty of his thoughts and just about the same bravery that MC had. He pursued his career in order to avoid having any more people like MC who lost his family to natural disasters.

Some would say that it's so cliche to have this one accident in a romance novel to cement the protags' feelings for each other. But genius author did more than that. It shows acceptance and of letting go. Not in the sense of breaking up (don't worry) but that if you love the other person, let them do what they've set themselves to do and support them all the way, even if it means facing so many more difficulties up ahead.

I felt like the author built it up as a fairytale teenage love story, but the ending gave us the reality of maturity.

It's so goooood. I love it so much. Plus, the Murmansk. The Arctic Circle nickname. The parallel universe where they did not grow up together. Aaaah. My LLB babie and my Surveying and Mapping Engineering babie. They suffered but ugh, the parents are very supportive.

I am not really a huge fan of the brothers (sorta) to lovers trope but the way Zhichu made it, it is soooo good. I love how Song Yu restrained himself until the very end and took care of Lele. I also love how Lele did not treat Song Yu's parents as his own (at first) out of respect for his deceased parents and because it'll be very awkward.
