Looking for the name of a manhua I forgot

I forgot the name of a BL manhua.

So the mc/bottom is mixed race, he has light brown hair and eyes (kinda orangish). I believe he might have a mental disorder(?) and severe allergies. The ML/top has blue-dark hair and eyes and is a few years older than MC. Their parents were friends but MC’s parents died when he was a child. One day, the ML’s father brought MC home and took him in.

The story setting is during highschool (plus university later). The ML tries to distance himself from MC because of his feelings for him. Meanwhile MC tries to get closer to ML and follow him. MC is the optimistic type. And ML is the quiet and responsible type that is protective over MC.

There was a scene during a school assembly where mc ate something that he had an allergic reaction to and ML immediately went to his aid.
