These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Tearjerker: Asami finally gathers the courage to confess to Ryouko... at the same time Ryouko is getting notified by Clarisse (her AI, not the MG) that she's being transferred.
Turned into a heartwarming moment in chapter 32 when after Ryouko's return from her mission and Asami's "resurrection", they start a relationship.
Ship-to-Ship Combat: While Asami/Ryouko, being the most developed couple is popular enough, there are a few fans who are interested in pairing Ryouko with Simona, Mami, Kyouko, Clarisse, and even theotherClarisse. There is Ship Tease all over the place and Ryouko is noted to resemble Madoka, who is herself the subject of this. In-universe, Ryouko is also considered as a Launcher of a Thousand Ships thanks in part to her extraordinary heritage and recent actions in the story. So far, the winner is Asami/Ryouko, with them starting a relationship as of chapter 32.
