After having finish watching episode 1, I must say this series is doing well for its ecchiness part, it really did things openly where Chizuru is taking the initiatives on Kouta.
I was abit confuse near the end where they talk how that building blew up but it makes sense that the beginning is just a few days/week after the incident and that the ending is just refering to how the incident happen.
This series reminds me of:
Mamoru-kun ni Megami no Shukufuku wo!. Although that show is about Beatrix powers, this one has the "Wolf and Spice" + Ecchiness-Romance in it which I find pretty amusing.
I'd give this show a go to those of you who likes the ecchi-romance-comedy genre, this episode at the end is what i find abit shocking lol i didnt expect they're going to do "it" it gives me the "omg what are they going to do after Chizuru nails Kouta down"!? idea
