One can only bend so far.

Even Compton knows that if an apology will ease a very difficult situation, it’s best just to say sorry (however un-heartfelt). The fact that Heejae can’t fully see/is choosing to ignore how much Garam is hurting, it just shows that at the end of the day all Heejae can fully value is himself. Garam is such an easy person to love, and he loves others so freely and tenderly. To lose that love and companionship over one’s hubris would be such a terrible loss.
