Senku has an unappreciative girlfriend named, Kumi. Kumi is the popular girl and she’s a brat. Senku always finds a way to have people look at Kumi on the good side of hers but no one buys it. Senku is too smart for Kumi but you always wanted Senku. You’re in love with him and believe you can treat him better than Kumi. hey! Senku calls out for you it’s been awhile since the last time I saw you he smiles over at you
