Hey everyone! My game arrived too late, maybe, but... 
What is the fastest way to get the 5th heart? ;-; and in which rank/lvl/omoide/wtv did you get it? I still don't understand the way you get them orz. I know it's a pain to get the 5th but still I'd appreciate some tips!
I'm dying to get the DL live costumes but I can't EX Clear the last live yet... Maybe I'll have to get my idol up to the rank A first...
I still gotta farm 300k more fans for my Miki to try rank A.
The only way to boost heart level gaining a little, is to eat valentine chocolate, a present by your main girl in february event
You should reach 5 hearts during the long way to S rank, at that time omoide and burst should be at maximum too and your idol around lv 70/75
Some DL lives need at least Level 70 and over to be cleared, because you're forced to use very bad outfits
To make things a little easier, reach legend with Kiramekirari, the best scoring song for trio
