The first volume is great. It's fluffy, cute, and leaves you with a nice fuzzy feeling that they'll get a happily ever after. Unfortunately they follow it up with the second volume that did nothing but ruin the happy fuzziness from the first volume. So my advice read the first volume and just skip the second, as it'll add absolutely nothing but annoyance and anger.

But he should have kept the long hair! As soon as I saw him I had the urge to sit him down in a chair and braid his hair. He would have looked so good with a long dark braid and I'm sorely disappointed at being deprived of the sight.
Yandere Taehyuk was definitely not on my bingo card for this series, but I very much approve. And well I suppose Taehyuk's level of crazy needs to match Hyo-Un's level of crazy to even things out. ╮( ̄▽ ̄)╭
