Then one day he met a man who claimed to be his deceased mother's old friend. He was told that his mother perished in a hit-and-run accident and that even now the culprit hadn’t been caught yet. Katsuya embarks on a journey to find the killer while battling his sinful feelings for his foster father, Tooru...

『She’s always putting on that grumpy face even though she’s not actually that upset! Oh, why can’t she just be honest with herself…!?』

『She is a tsundere, after all? When her embarrassment levels exceed a certain limit, she will explode into anger. However, the point that she’s suppressing under the surface is that she wouldn’t mind that sort of thing if it were in a less public place.』

As Endo-kun passionately reacts to the antics of Lady Liselotte, the villainess of an otome game, Kobayashi-san provides a painstaking breakdown of her tsundere behaviour.

Suddenly, one person could hear their voices; Liselotte’s fiancée, Prince Siegward.

What on earth is drawing these feelings?
