Finished the novel. The story is overall fluffy about their relationship but there's a bit of angst towards the end with one character's death and their past is just sad. TvT my poor Xie You, my poor Nian Nian...

Minor character. Spoiler:
It's a minor character death. Later on Nian Nian and his father will be reunited but father is already very sick. At first they weren't gonna acknowledge each other, father because he didn't want NN to be sad and NN coz he never thought to find his father. Things happen and they got closer. NN was always with his father, talking with him through video calls and staying by his bedside during his final days until one night NN woke up running to his father's bedroom and father's health started failing with no hope of recovery. It was sad, but xie you was with him throughout all this.

The English translation stops at 3 chapters. I MTLed the rest of them. Here's the link for the English translation. https://www.novelupdates.com/series/i-heard-that-i-am-poor/
You can google the Chinese title for links of the raw novel.

This contains spoilers.
If you think there's BL in this story, you're right. If you think YF will end up with JC, you're wrong.
YF doesn't cut off relationship with JC but they're like good bros. Sometime later in the future JC would risk his life to protect YF, taking a gunshot for him and almost dying so YF owe him his life. JC also declared he loved YF and he can't find another he love except him but YF doesn't love him. YF later got his own girl, got married too and he also has a child. JC's life goes on, almost got married to a girl but the girl ditched him before marriage. JC took in the girl's brother, and later on developed relationship with him. It wasn't happy and fluffy always. Ji Junxue sometime later got kidnapped and sold to Feng Tian Leng, YF's subordinate who fell in love at first sight with JJX. There were forced kisses, skinship and rough manhandling but FTL loved JJX too much he didn't force him even when he bought him with an enormous amount of money. JC found out and was gonna fetch him but things happened and he stayed with FTL and JJX as YF's guest. JJX found out from FTL about YF. When he saw YF, he felt inferior to him. JJX parted with FTL. He can't love him but I felt he perfectly friend zoned the guy. Extreme case of second male lead syndrome here. FTL told him that if JC wronged him, just return to FTL, his door always open for him. JC's dad didn't approve his gay relationship. Gong fam wants JC to marry their daughter so Jing family would support Gong fam. Gong girl did many things, finally drugged JC and blackmail him into marriage. It wasn't aphrodisiac drug but it made him stay drunk in and out of consciousness. Next day JJX found JC in bed with a girl and was devastated until he saw it was Gong girl who always wanted his despair and pursued JC. He pushed her away and took care of JC and told her he trust JC. Then JC woke up hearing this, agreed with him and told the guards to take her away. Gong girl struggled and fell down the stairs, broke her legs and hurt her lumbar spine. The marriage's off and Dad Jing accepted JJX into the family. Forgot to say, even though it was not recognized in their country, JC and JJX are legal spouse. JC even told his lawyer how could he marry Gong girl when he already have a wife.
Alright that's it. I don't really remember much since I skip some chapters and my understanding of them are limited since it was machine translated.

I relied on MTL when I was reading so the names probably won't be the same for when the English version come out. The 2 person you asked won't be appearing anytime soon, they're waaaaaaay close to the ending when the story I mentioned in my spoiler took place. If we have to compare with the current scans, right Now the English scan isn't even halfway through till the end.
This Lana is dumb, isn't she? Letting the guy live when he's holding a grudge not only to herswlfbut also her savior? Wow, when others had already contributed to making sure no traces are left but leaving the guy go alive. So dumb.
