May I submit to you; Nirei starts hanging out with Sugishita, and Suo gets /jealous/ (either romantically or as 'that is MY bestie I did not give you permission to pursue')
BASIBDISBSOSJSOWBWISKSIJSISBSIJA I LOVE BOTH WAYS!!!!!! I have some ideas now that you mention it!
Romantically (they're dating): 🫖 becomes clingy, hugging Nirei from behind, hiding his faces in 📒 neck
🫖"did you have fun?"
📒"Yes!! Sugishita-san was calm and very serious about Sakura-san's info!! He let me yap about him! He was also very sweet!!"
🫖"...I see"
📒"oh! And also Sugishita-san was-"
🫖 Starts kissing 📒's neck in a soft way
📒"S-Suo-san?"
🫖"Shh, it's okay, let me spoil you a bit"
🫖 just wants 📒 to stop thinking about 🌲 (🤭)
Platonically:
📒"it was very fun to spend time with Sugishita-san, even tho it was kinda scary"
🫖"uh"
📒 "I hope we can become closer friends someday"
🫖"No"
📒"eh?"
🫖"mmh?"
📒"what did you say?"
🫖"nothing ^^"
Later
🫖"stop stealing my best friend"
🌲"?"
(I prefer the romantic one but I like both!!! 🫖 jealous is my fav thing BCS HE IS DEFINITELY A JEALOUS GUY SORRYSORRYINEEDTOCALMDOWNABITHEHEHHEHEHE)
