WHAT

Years ago kirishima gets hit with a quirk where if he makes eye contact with bakugo he would forget all memories of each other.

Beginning of story : Kirishima is holding on to bakugo body crying and asking his name and. Then he realises he is crying over a complete stranger.

During the mid : this is past event. Kirishima gets hit with quirk decides to stay away from bakugo and be in touch from far. Years pass bakugo decides to return Japan where kirishima is. He reaches airport and the accident occurs.

End of story and the conclusion : hero kirishima comes for rescue and he sees injured bakugo and he is happy to see him after years but he cries as he is on death bed almost. He rushes towards bakugo taking him on his lap and crying and in the meantime due to eye contact the quirk activates and he stars to lose the memories. So in the end he forgets bakugo but he was still crying and couldn't understand why.

And the painting didn't have huge significance. Only that it was somehow related with their situation. Bakugo and kirishima waiting for each other but unable to meet for the quirk. But in the end the dolphins bring bakugo back to kirishima only to lose memories completely. （/TДT)/

Thanks for explaining! Tho I thought the dolphin brought memories back despite the quirk activation
