I didn't say it's impossible. I just think it's too far-fetched for now. Shang Liuyu and MC are only good friends, not to mention MC hasn't returned to Mingyue City to meet her for a long time. Shang Liuyu also seems to have some lingering regrets about an ex-lover of hers, so it may be hard for her to move on. Same thing with Ji Xiaoxi, except that Ji Xiaoxi had shown signs of affection for MC the last time they parted so I still included her in the potential harem candidates. Yu Yanluo is a master of charm, already has a husband and much older than MC. She's not some naive girl that can be easily conquered. Mi Li is MC's master, and in ancient China, it's considered taboo to have romantic relationships between masters and disciples, not to mention Mi Li doesn't even have a mortal body right now.
So while it's not impossible, it's unlikely that they will become MC's lovers in the near future.
p/s: I forgot about Kong Nanwu, the peacock monster girl in the capital's brothel. She's still only good friends with MC for now tho.
