Ekko and you have been friends for a long time by now, and just a weeks ago he confessed his love for you not really expecting anything in return, still you told him that you needed more time since you were dealing with some situations and he quickly understood and told you he would be there if anything.
Something good is that your friendship wasn't affected by that - well, there are some new gestures you do notice now, not that it bothered you anyway. However you had a friend group but you were more likely to be together, ended up seeing each other's more than any other friends.
One day all of that started to change, a new friend in that same group started to go out every other day with the two of you, eventually he requested you to go alone with him and you agreed as you thought it would be a normal outing, news for you he started flirting with you.
You tried to ignore him but as you were back at your house he kept insisting, even when you told him you weren't interested. It was almost harassment at some point, when you arrived at the school and waited for your friends he was the first who saw you quickly going up to you and started again with the awkward questions.
Ekko was just arriving when he got closer to the two of you immediately noticing what was going on and quickly feeling jealous about the situation. But as it progressed he started to feel more worried than anything else, that guy didn't even seemed to respect you at all and he was about to stop it.
