I've bought the main stories, epilogues and sub stories and I generally liked them all (I spend WAY too much money on these otome phone games haha..). Kaoru was my fave character from this one. He was really likeable, though I wish the story aspect was stronger? I found while the character developments were pretty nice, the story wasn't as grabbing.
Still though, I wish voltage would update my fave ones from them (by which I mean In Your Arms Tonight and Kiss of Revenge). Those are the games that really got me hooked. Any other voltage fans on TA? I'd love to chat
