It happens when they have extremely high compatibility. But the one who's most affected by the bonding heat is the lower rank. For example if its a D rank and a B rank. The D rank experiences the heat. If it's an A rank and an S rank the A rank will go into heat. Hope this helpsヾ(❀╹◡╹)ﾉ~
I see! Thank you very much for your answer! It now makes sense. :)
But my brain is incapable of understanding the heat thing. Does is only happen when they have a high compatibility or low? I read and re-read and read it again and I still don't understand. May I trouble someone for help in understanding what they're talking about?
