Chn pre-explanation of Mimo's childhood traumas would have invited them and thought it to be a grand gesture of love. Post-explanation Chn would rather commit first-degree murder than invite Mimo's parents to experience such a beautiful and vulnerable moment for both Mimo and Chan

So, if their mating ceremony were to take place now, then Chan wouldn't even think about inviting them - tbh, he would probably ensure that they were incarcerated to be 100% sure that they wouldn't be able to ruin one of Mimo's most memorable moments in his life😌
