It's hard to really judge this series, because I'm influenced by the webtoon and because the content is so similar that my interest is not huge, which also means all the writing flaws of the webtoon exist here too, which are enough.
In this volume it's more about Taeui and Ilay and how they interact more due to circumestances and how slowly Taeui gets to learn about his existence as a "lucky" charm for his brother. It's more of a foundation book, which builds on their relationship and Taeui's further role.
Ilay is a psycho, but a likable one from afaaar and also, I really liked the hidden track, which existed in the webtoon too, but it was so cute regardless.
