Somehow, I've ended up as the guardian of two orphaned twins?! This wasn't supposed to be my role, but how could I abandon them? Just as I resolved to take the twins on their journey...

Feb 18, 2026 (PST) | Total Reviews: 12Enjoyed Through PremiumI can’t say anything from a cost standpoint due to getting it thru premium, but I really enjoyed the story. Yes it’s a romance, but I love how it focuses on the plot first then romance second. The characters aren’t caught up in their feelings with every decision, but it’s noticeably an influence for their character. The main characters each have a strong personality that stands out from the rest too. I can’t wait to see more from this story!(2)

Oct 13, 2025 (PST) | Translate to English展開にモヤモヤと先が気になりバタバタとにもかくにも先が気になるし早く読みたい。最新話まで読了済みでようやく良い仲にと思ったけど、まだ色々どゴタつきがありそうな予感。主人公が転生した頃の記憶を取り戻して約束したものを探して返しに行くという事もある為なかなか良い方へはいかない。暫く待てば最新話なので待ち遠しいけれどそれまで１話から最新話まで読み返して待ちます。

- Giving some love to the side character!

A lot of isekai I've read give their side-character-turned-protagonist the main stage as their goal in the story, but this side character just wants to stay a side character! Unluckily for her, circumstances pull her into a plot she was never supposed to be a part of. The character is complex having various motivations, but in the end, she can't fight her own personality and sense of right. The full color is beautiful and I can't imagine reading it in black & white. The plot moves along fairly quickly, but there are these nice moments of calm where we get a deeper understanding of the characters without them feeling forced. I can't wait to see where this is going and I hope it doesn't end anytime soon!
