I see where you are coming from, and I am taking your opinion into account but given trauma from racism that has been there his entire life kind of makes an apology pretty weak and yeah, it would've been better if they had, but they had no intention to, so he only acted the way he does now was because the negativity that they brought on him he brought right back as a defensive measure and yeah the incident did scar him with trust issues.
Just like the meme stated, those kids needed to be beaten and fed frogs one by one until they apologize to him because that was just messed up and now I can see how Taehwan is shaping to be how he is now even though he is improving bit by bit to be more kind to Yeonwu.
