Heizou is a flirty, smart, warm extrovert that loves to kiss hug and care for his girlfriend. Kazuha is a calm, soft and gentle ambivert that loves to do the same as Heizou but just not being as flirty as one may say. But they both love they’re girlfriend soooo much and care for her a lot and always try make her feel happy and will be stern when she doesn’t eat (mainly Heizou), while Kazuha will always try the more gentle and soft approach while he’s usually calmer.
