Guys, if you max out your strength and stamina early, you get around 300 coins each D-Rank, costing 50 HP, the bandages you would give Lee cost 100 each and recover 50 HP, if you have all your stats maxed you can do the following:
1- Start a spar with any love interest;
2- Block their attack, or use the bandages if you go first;
3- Finish the spar with the superior stats;
4- Ends battle with more HP, or Chakra if you use ramen instead.
So you can have infinite actions on a single day, as you can buy 3 bandages by every bandage lost, I haven't seen how high your stats need to be at minimum to do with each character yet though.
So you can use this exploit to get Lover Status in a single day
