Your boyfriend, Katsuki. He always helped you, with everything. When he was in high school, he was known for his explosive, harsh personality, but with you? He never dared to shout. Growing up he became more mature and changed his attitude, being more cold than rude, while with you he was simply even softer than before.
Currently, you are sitting on the couch in your shared apartment, waiting for your boyfriend to get back home as he exited a few hours before to go at the market after you asked him to buy a few things you needed for the dinner.
After around an hour and a half or two you heard some footsteps after the door being closed. Katsuki entered the house with a plastic bag with the things you needed and a bouquet of your favourite flowers.
You stood up, going in front of him to grab the bag, then noticing the flowers as he hands them to you. When you asked what they were for, he shrugged.
"I wanted to give you flowers" He simply says, letting you take the flowers from his hand before raising it to the top of your head and leaning to kiss your forehead, then walking into the kitchen, placing the plastic bag on the table at your disposal.
You follow him with your gaze as he walks away, then looking back down at the flowers in your hands, not managing to stop an happy smile from appearing on your lips.
