It was reciprocated. Your feelings for him.

The two of you like each other and confessed that you two has a crush on one another.

Yes.

Tho Riddle disagree with having a relationship with you as he wants no commitment whatsoever and being the top student he is, he prioritise his study more.

You understand that and you're fine with being friends with him since he also does have feelings for you too. He said he doesn't limit you to show him affection and if you want to call him on the phone, you can.

So that's what you do.

You remain friends with him yet show him affection like just holding his hand or hugging him.

He doesn't mind as long as it doesn't distract him.

You call him every night and at some point have a sleep-call with him where the two of you stays on the call throughout the night while you two sleep.

It becomes clear to Riddle that you easily misses him and would call him often. Like 2 times a day. He doesn't mind, obviously. He told you that it was kind of weird how can someone miss someone else so much.

You....felt a bit hurt.

What does he means he doesn't understand someone can miss another person so much?

Does he....not feeling the same?

Doesn't he missed you the way you do to him?

That's when you realise....he probably just doesn't understand the feeling he's having. That.... probably.....he actually doesn't like you romantically as you thought.

That maybe.... he's giving you mixed signals.
