Japonica Logos: Love; Answers

Here are the answers to the questions on the "Love" edition of "Japonica Logos."

First question: Which word means that you want someone all to yourself, "Ai" or "Koi"?
Answer: "Koi."
Host Tamori explains his understanding of the kanji for "koi"; the bottom part is the heart; the middle shows that the heart is on fire; on top of all that is a lid shutting that all in, making the feeling intense.

Question 2: Which word describing flirting has a more negative connotation, "icha-icha" or "beta-beta"?
Answer: "icha-icha."
"Icha-icha" seems like you are flaunting your flirting behavior for others to see; "beta-beta" has the meaning of clinginess, but for couples with established relationships, it seems kind of natural for them to be huggy or together.
This picture shows the dictionary definition of "icha"... it originally meant "a young girl" and thus, "icha-icha" has the feeling it's done by young couples.

Question 3: Which word can actually mean "OK," "yamete" or "iya"?
Answer: "Yamete."

As these pictures explain, "yamete" means to "stop this action," but "iya" has a stronger feeling of disgust or dislike.

Question 4: Which word means you may like the person, "ikenai hito" or "warui hito"?
Answer: "ikenai hito." "Ikenai hito" connotes a naughty person, but "warui hito" means the person is bad or evil.
