Is it proven that Kim Soohyun groomed Kim Sae-ron?

I'm not a supporter of Kim Soohyun, but I'm just wondering if it has been proven that he did groom Kim Sae-ron. Please send links of proof if possible.

I saw that apparently his lawyer was able to prove in court that he was indeed framed by his accusers (the Youtuber and the Family of Kim Sae-ron) by showing that the evidences provided were manipulated/fabricated. I also saw that Kim Sae-ron's family has been money greedy for a very long time and even used her (so it is very much possible that they are doing this simply to get money from Kim Soohyun). Anyway, based solely on what happened in court, it seems the evidences shared by the Youtuber and Kim Sae-ron's family are not credible at all. I've seen people who hate Kim Soohyun base their hate on the released "evidences" of Kim Sae-ron's family and such. But, given the fact that the court deemed their evidences were not valid, I personally cannot believe those who hate on Kim Soohyun wth innacurate evidence. So, if you can, please give me credible proof that shows that Kim Soohyun indeed do what he is being accused of.

Also I'd like to note that as much as Kim Soohyun is being hated on, I honestly think, Kim Sae-ron's family deserve just as much hate and even deserve to be put in bars for basically abusing Kim Sae-ron (which might have been part of the reason she died).
