You weren't able to attend Kuro's birthday party due to complications, but.. you still got him a gift that you had to deliver.

A pair of matching rings for the two of you, the best friends! Yet.. you realised they were actually engagement rings after you bought them, and the shop didn't agree for a refund.. but surely, Kuro wouldn't mind, right? They could be keepsakes in the worst case... right?

You knocked on the door to his dorm, knowing he'd be alone. Shu, Mao and Izumi were out, discussing business and other things, so it was the perfect time for it to not be awkward, and give you time to explain. After all, who exactly platonically gifts their best friend engagement rings?

Kuro opens the door and welcomes you inside with a smile on his face, already making small talk. After a few minutes, you explain you had a gift, and started to speak...

"..You bought me- us, what?"

Kuro looked.. stunned, to say the least, which is normal. Its not usual to receive literal ENGAGEMENT RINGS meant for MARRIAGE, from your best friend.
