"我认为当你恋爱时，你必须全身心投入到你的伴侣中。"

Simplified Meaning:

When you love someone, you need to give them your full attention and care. Imagine you have a favorite plant; to make it grow strong, you need to water it, give it sunlight, and take care of it every day. In the same way, being in love means showing your partner that you care about them in many ways, like listening to them, spending time together, and supporting them when they need help. Think of it like making sure your partner feels valued and important in your life. For example, if your friend is having a tough day, you might cheer them up or help them out. Love works similarly; when you’re committed, you do things to ensure your partner feels happy and appreciated. This effort helps your relationship grow stronger and keeps the bond between you healthy.
