Vol 4: Ch 176 - Unexpected fight between the two Main Vocalist of the team
After hearing it from Je, everyone gulped except Tae. Rei didn't expect that this two will fight because of her. Rei knows that Tae is not like this and she knows why Tae doing this now, because of her and of course because of his insecurities and jealousy. Rei knows that Tae will solve it and she trusts him because she's aware of how much Tae values his teammates especially Je who's the closest of him among the Team Members. The team didn't butt in between them because they also know that the two vocalists of the team will become closer after this unexpected fight from them so they didn't stop them and just let them be, well they on standby in case it will be getting worst.
