This was ridiculously good! I can't even condense it down to words: it's romantic, sensual, humorous, everyday, heartbreaking, fluffy, dark, but always, always so beautifully real. I love this atmosphere of tension, of how Nino spent so much of their relationship sizing Jun up, feeling him out, always probing, always keeping himself "opaque" and not realizing (or maybe realizing but denying) how he's losing himself in the set of rules he's boxed himself into. And Jun! I love this Jun, every inch the gentleman, polished and refined, doesn't blink an eye at all the unconventional things he and Nino do, yet still so tender and attentive and basically a ball of mushy mushy goop deep down inside. And the way these two danced around each other, each afraid to advance-- oh anon! You've woven this story perfectly. I mean, we all know how a story like this is going to end. We all know that they're gravitating towards each other and that there will come a point when the forces of attraction are too strong for them to maintain the status quo. But your writing, with the sprinkling of little revelations through seemingly mundane details, makes every word worth the read. Thank you for such a beautiful, romantic fic!
ETA: Loved the Aiba/Nino friendship and bless you for writing Tennen as a side pair!
