Xia Wanying
Understanding Li Lei (at least with what we know), he's not that type of person, just... if later on Xiao Ling is in trouble and Li Lei saves her again, I hope he doesn't force her into anything. Xiao Ling has been through so much, please don't be a second Pei Ziheng (to a lesser extent, but still...). I just want Xiao Ling to be happy...
Hmm... I quite like Li Leo, he's pushy, but not overbearingly so. He has a reason to be pushy as well given that she's pretty much spurned his advances at least twice, pretty much any other male in any other novel would have been at least annoyed but Li Lei doesn't seem to outwardly mind it at all here beyond reminding her that she needed his help not vice versa.
