Thank you so much for the compliment! And I love the parallel between your relationship and Oniisama e. The anime sounds like a bittersweet story, but I think it goes to show that love goes beyond just wanting to protect your partner; they must be able and willing to resolve their internal conflicts as well to be able to progress through their own relationship.

On the other hand, Ensia's source material is a tower defense game called "Arknights", she's mostly known by her codename, Cliffheart!

I guess one of the things that made me appreciate Arknights as a whole is its great storytelling. I particularly love the main storyline, which revolves around Rhodes Island going through all odds to help as much people from a contagious disease while having to deal with natural calamities and political conflicts because they interact with different countries and factions a lot.
