You cannot fall in love without going through this process: being seduced → being bound (loving) → being bound (affection/love).
SEDUCED is the first phase that happens without you knowing it: you automatically feel in touch with the charming person. Tempted happens automatically in the subconscious, connected with the body's biochemical reactions and psychological maps that are embedded in the self.
BOTH (to like) is the second phase when you realize that you have a special interest in someone you like. THINKING is not just a subconscious desire anymore, but also conscious and always logical reasons.
BINDING (affection/love) is the third phase AFTER you consciously and intensively invest in someone you like. This investment can be in the form of regularly contacting him every day, often treating him to meals or watching movies, paying for his lectures, buying him various kinds of gifts, and so on.
Humans automatically have an emotional/psychological attachment to something they "manage" by spending energy, time, and money. That is what is meant by INVESTMENT, which is using personal resources to manage the continuity of a relationship. The more you INVEST, the BETTER, STRONGER, BIGGER, and DEEP you love that person.
Affection is the feeling of ASSOCIATION / LIKE that builds up because you are Tempted first and then RAIN INVESTING in the person you are interested in. This affection is what is known by the popular term: Love, because it is mature, binding, valuable, and long term.
So, a healthy love relationship can only emerge if the RELATIONSHIP ARE ALREADY WORKING, marked by both parties agreeing to work together to provide mutual investment. So when you approach, you should not invest a lot unilaterally, so that you don't love too quickly, aka premature love! Imagine if you were the only one who invested, while the crush wasn't. You can guess who loves and who doesn't, right?
