Ever since yesterday gray has been feeling hotter than before, he tried to use his magic to cool himself down but it has not worked very well.

He groaned when he seen Erza come in his direction, "yeah?" He panted but shook his head. She gave him a very concerned look and knelt down, "are you alright gray?" She asked and he shook his head. "No, since yesterday this shit got worse" he told her and he panted more. "What happened to get you like this?" She asked and he honestly couldn't explain it himself.

"Well yesterday, lav was holding her stomach like she was in pain then when I went to check on her I started to smell marshmallow's. Even she was confused with that" he told her and she raised an eyebrow, "marshmallows?" She asked again and he nodded.

"Okay, that's weird. Let's ask the master and see what he says on that" she told him then helped him up and they both walked to the master's office. she knocked and then received a reply and opened the door.

"Master, I have a question about mating season" she told him and they both walked to his desk. "Yes Erza? What is it?" He asked and she explained what gray told her to master Makarov. "Hm, I don't much about dragon slayers heat but I do know that if their mate smells something then that means that's their mate scent." He explained and gray blushed.

Cause he too has a crush on lavender but doesn't want to get rejected.

"Wait a minute, Lavender's my mate?!" He yelled and Makarov nodded. "It seems so, gray. You'll need to mark her before someone else does" he told gray but he's still taking this in.

His crush is his mate.

"Thing is I don't know how to tell her, after all I doubt she'll even want me as her mate" he explained and the master sighed. "If you don't mate with her soon then the effects next year will be more worse than they were this year" he told gray and both demon slayers looked at each other with worry. "Thank you master" Erza told him and both demon slayers left his office.

"Gray tell her" Erza urged him but he shook his head. "What am I supposed to tell her? Hey lavender I'm your mate and if you don't mate with me then the heat effects will be worse." He grumbled and seen her with the other dragon slayers.

He sighed. "I can't Erza, if I confess my feelings for her then our friendship will be ruined of she doesn't like me back" he explain and she sighed. She placed a hand on his shoulder with an expression of worry, "just, just tell her how you feel soon. Who knows what'll happen if you don't" she explained then walked away.

He looked back at lavender, her and Lucy had a great friendship and he didn't want to risk his with her.
