I saw some people not liking how overconfident Mai is and I completely understand because I'm not much of a fan of pushy characters... tho I don't think she forced Renako in kissing. If she did, she wouldn't have paused and gave time for Renako to stop her. I think she simply wanted to see if Renako knew her intentions and she seemed satisfied that Renako understood her gesture.
But she didn't push it at all.
I'm excited to see if ever Mai would have a charac dev where she would be less pushy and act more humble, that'll be interesting. I'm also looking forward to how the two of them would appreciate that being friends and/or lovers has its own strengths and weaknesses.
In the end the comment section is right, your lover should be your best friend while your best friend can also be your lover. I'm betting that no one one in this game
