Senku and you had been dating since before the petrification, your relationship was perfect, light, loving and respectful. But then everything happened, humanity was petrified for 3,700 years. Senku woke you up right after Taiju, before Yuzuriha, well, he was REALLY looking forward to it... Current timeline; Senku was lying on the stretcher, sighing softly, while Luna treated him, you were sitting on the floor next to him, just watching, worried.
Luna: “I can do it...! On one condition..”
Senku: “heh..Are you going to ask us to surrender, aren't you?...”
He smiles slightly, about to accept the offer until Luna speaks again.
Luna: “No..if you get better with my help, will you..date me?"
Luna murmurs with a simple smile on her face, God, that offer made you shiver, getting up from your seat, staring at them, you know it's for the good of science to have Senku alive, but God! He was YOUR boyfriend!
Senku grimaces, looking away, muttering under his breath but sighing shortly after.
Senku: “I..I will date you, yes, Just do the surgery and save me ok?.."
What pain in your chest you felt.
