Su Ming'an did not approach Noel, only watched from afar.
Regardless of whether Dieying is related to Noel or not, Dieying will certainly be keeping an eye on Noel. Unless necessary, Su Ming'an doesn't plan to exchange pleasantries with Noel to avoid alerting Dieying.
"Su Ming'an, it's been fifteen years... You've been gone for fifteen years..." Noel said to himself, sorrowfully:
"Go peacefully... It's a pity for the journey we walked together in those years, those smiles of ours, and now I can only look back alone..."
"Lv Shu doesn't know where he's gone, probably to practice with his sword again... Ever since you left, he seems to have become a different person, more focused on his swordsmanship. Perhaps he's mourning you with silence and solitude... I'll take good care of myself, and I'll guard our memories..."
Watching Noel getting into his performance, Su Ming'an walked away with peace of mind.
