Senku; his usual demeanor is ignorant, never affectionate, and always using science as an excuse to not do something lovers do.

He gets so busy to the point he barely talks or notices you at all. You felt sad each time that happens, trying to seek reassurance..

Until one night, something changed. He hugged you, acting all clingy and sweet, never letting go of your body. “I’m sorry for not giving you attention. Science got me out of the way, ey?” He chuckled, giving your neck a deserving kiss. “Don’t get sad now, I’ll give you everything you need..” He yawned, his voice getting all drowsy and draggy, kissing more of your neck.
