Otome Chat Connection is a new game made by SEEC, featuring text conversations with different characters. When having conversations with characters, you are given three choices: each one is either Excellent, Good, or Bad. Excellent usually increases heart percentage by 4%, Good increases by 2%, and Bad decreases by 2%.
In order to unlock the date stories, you must have at least 80%. And in order to unlock the Epilogues, you must complete the initial 8 characters as well as completing 96% or higher for each character.
