In the novel; Did you know that When Renji and Rukia announced their marriage at "The Safflower," Nearly everyone they told was completely unsurprised by the news ?😂😂 Only Hanataro and Hisagi were shocked (Hanataro briefly fainted, and Hisagi was called a "thickhead" for not figuring it out). Those who had already figured it out and were not surprised included : ​Rangiku: Smirked and immediately knew it was coming when Renji sent the morning email without specifying what the "important announcement" was Yumichika and Ikkaku: Figured out that an unspecified announcement meant a wedding. ​Hinamori Momo: Agreed with Yumichika and easily deduced the news beforehand. ​Kiyone Kotetsu: Realized it as soon as she saw the high-class, formal setting of the restaurant. ​Kira Izuru: Put together the luxurious location with the nature of the gathering. ​Hitsugaya Toshiro: Remained calm and supportive throughout, not showing any surprise At the Captains' Meeting (Chapter 14) When Kyoraku announced the news to the Gotei 13 captains, he popped a party cracker expecting a big reaction, only to be dejected when literally every captain already knew😂😂😂: ​Soi Fon: Stated it was only natural she had intelligence on the matter. ​Rose: Already heard it from his lieutenant, Izuru Kira ​Kotetsu Isane: Already received the news from Rukia and Renji directly. ​Hirako Shinji: Already knew through Hinamori ​Iba Tetsuzaemon: Was already personally greeted and told by the couple ​Yadomaru Lisa: Already knew (and was already taking wedding-kimono accessory orders from Rangiku) ​Muguruma Kensei: Knew because Hisagi was desperately asking to run a magazine feature on it ​Zaraki Kenpachi: Knew because Ikkaku and Yumichika wouldn't stop talking about it ​Kurotsuchi Mayuri: Knew everything, including Urahara's secret gift to them ​Kuchiki Byakuya: Had already personally approved the marriage, processed the paperwork, paid for the restaurant, and secretly scheduled their ceremony.
