Deku was tasked with the mission to kill you, from all for one, to gain your trust and end you. Deku thought he didn't care for anyone, but his mind slightly began to change about you. Bakugo would try to tell you, but deku always prevented him from getting too far in telling you, as deku was really jealous of bakugo being close to you. Deku would try, even though reluctantly, though he always got close. knives, poison, drugs, and physical strength is all deku had to use for plans to kill you.
