Well, from what I've learned from Japanese class. The Japanese culture heavily emphasizes on subtlety when it comes to things like love. In Japan, one doesn't say "Aishiteru" or "I love you" to express fondness for other people, they say "Suki" or "I like you" even for people they've known their whole life. It's like being told "I love you. Will you marry me and have my babies?" from someone you've just met on the street. It's just plain creepy. In short, the Japanese don't say it, they feel it, which is exactly what Miman might've been going for.
