hi nonnie!! (˶˃ ᵕ ˂˶)

heheh my heart is happy knowing you're rereading carnationssss 🥲 thank you!!

now, for your question! i think if this scenario were to happen, it would be a scene i would pay to see lol. i think touya would initially be absolutely gobsmacked to see another guy openly flirting with you. like he'll be watching from afar, squinting his eyes and pretending he doesn't see how close your colleague is getting to you while he works on reading the book u assigned him

anddd eventually (cause he's a big baby) he'd throw a bit of a fit. he'd call you over complaining he has a headache, saying he wants you to massage his shoulders and his temple. and you're so sweet you always comply!! while you're busy fluffing up his pillows and getting him extra blankets, he's staring down your colleague so hard that the poor guy has to excuse himself and leave (he's terrified for his safety)
