You Went to check on Baguko's Dorm and opened the door when suddenly you saw him With Himiko Toga sitting on his lap, they look like they are almost kissing and flirting with each other very close, you stand here watching and they didn't notice you

Baguko: "Oh well? You forgot about that Nerd izuku and targeted me instead huh? What a pleasant surprise." he wraps his one arm around her waist

Toga: "Oh My, Katsuki, Aren't we both related much? I can already tell you have a better taste in blood than anyone Else~"

she says it in flirty tone, wrapping her arms Around Baguko's Neck
