Min isn't wrong for being angry. He's not childish or petty or wtv. it's normal to feel insecure. iss not given to everybody to be confident and to fully trust someone. Sujun and him have just started. And its normal that he doesn't fully trust him yet.
Trust comes with time. Specially when you've been played with like Min. And he's frustrated. So Ig he had to let out his frustration. And it happened to be this situation.
But im glad that when he saw sijun cry he didn't extend this drama and all. All of this forms part of a relationship and love. Now the fact that they break up, it's probably because he doesn't want people finding them out to ruin sijun career. Ik it's not something childish. He's not childish.
it hurts. when i saw bakugo opening his eyes and talking, my eyes teared. i was so relieved. shoto's expression looks like he might cry at any moment. i mean he's still a child. they're still children. wow. AND that panel where bakugo genuinely ask about deku todoroki he looks so soft, when he hurried to deku. THE LAST PANEL WHERE TOSHINORI HOLDS IZUKU'S HAND.
