hmm ill try although im a bit confused too
If Deku founds out that he is in Danger, and Bakugo has the antidote, means Bokugo need to left his mission for Deku
and I think Deku rather being in danger than making Bakugo comes to him. So by switching the role, thinking Bakugo is in Danger, Deku will definitely ran to him
I think Bakugo thought that if Deku knew he was poisoned, he wouldn't want to disturb Bakugo with that and just die. But if Deku knew it was Bakugo in trouble, Deku would do everything in his power to help him. So Bakugo used that in his favour, if that makes sense
I don't actually understand what Bakugo explained. Like...what does he mean? Will Deku still choose to die so as not to bother him if Deku knew the truth? Is that it? Someone please actually explain shit to me ahaha
