I think it was because the friend was going to yet again out him publicly (people were gathered around when he was gonna call shiro his boyfriend) , and on top of that, he was not being mindful of makato's feelings at all and i believe was going to say some manipulative stuff to make himself seem not at fault.

im just confused about this so im just gonna ask. im at ch3 rn and... im confused why makoto is not letting the friend talk? i mean it's really bad to trick your friend into doing something but makoto really didn't want to hear him explain/apologize when the friend wanted to talk with him (which imo could've been good at least to give them more of a resolution rather than forcefully shutting the friend up/out).
am i missing something here? in asking cause i want to understand somehow.. more from makoto's pov at least. cause with what im getting right now, if i were in the position of the friend, i would really feel frustrated not being able to explain or talk to him. it's sad when things get left hanging like that after all. i mean this prolly get resolved in later chapters but the way they shut him off bothered me...
