Back on November 29, rookie vocal duo B.O.Y greeted fans via their first 'V Live' broadcast since announcing their group name. 

During the broadcast, B.O.Y's Song Yoo Bin came across a malicious comment, which he chose to confront rather than ignore:

Song Yoo Bin: Huh, this person is cursing? XX-nim commented 'Shut up'... so I will respond with 'Reflect'. Reflect!

Kim Kook Heon: Kekekeke.

Song Yoo Bin: I won't shut up. This is a place for us to communicate with our fans.

Kim Kook Heon: Good way to handle it. 

Song Yoo Bin: Would you say that again please? I got a little angry just now. Sorry.

Kim Kook Heon: Hahahahah.

Song Yoo Bin: My face is a little red now. I'm sorry. But you shouldn't curse. Malicious comments don't belong here. Please don't curse. Ah, I'm sorry, let me calm down a bit.

Kim Kook Heon: If they leave another malicious comment, let's respond with 'Rainbow reflect'.

Seeing the idol's active response, netizens commented, "He's got a refreshing personality", "'Rainbow reflect' kekekeke, that's a pretty good move against malicious comments", "That's what I like to see!", "Yes, cut off people who need to be cut off!", "Kekekeke I like this kind of reaction", "Why would you actively seek out a live broadcast and then leave a malicious comment anyway?", and more.
