LOL, yeah, I was definitely looking through that gallery the last few days. XD

Pretty sure this one (https://lovenikki.fandom.com/wiki/Story_of_Shanghai) is also chrysanthemum. The Return to Autumn is 100% chrysanthemum. The only other ones I can see that are obvious chrysanthemum themed are this (https://lovenikki.fandom.com/wiki/Golden_Dragon_of_Neck) and this (https://lovenikki.fandom.com/wiki/Oceanic_Spirit).

BTW, for wintersweet, there's also this one (https://lovenikki.fandom.com/wiki/Cold_Red), this one (https://lovenikki.fandom.com/wiki/Beauty_in_Painting), this one (https://lovenikki.fandom.com/wiki/Fleeting_Life_in_Snow), and this one (https://lovenikki.fandom.com/wiki/Response_to_Crane) - that last one is a very classic crane + wintersweet theme. Personally, I really like Cold Red.

Meanwhile, there's this one (https://lovenikki.fandom.com/wiki/Inked_bamboo_Slip) for bamboo, although it's super subtle. I personally prefer Green Spotted Cornel and Bamboo Song myself.

Not gonna lie, I've been looking at the pictures for inspiration for NaNo - planning to write a "four gentlemen" themed magical girl story. XD
