Jiang Cheng x Female reader : Childhood promise

Past

" AAAHHH A DOG ! SAVE MEEE !", Wei Wuxian cried and climb up the tree . Jiang Cheng run over to chase the dog away . Wei Wuxian don't know how to climb back down and he's crying madly ." Here Wei Wuxian , jump down ", I put my arms out . He think for a moment before jumping into my arms . He sob on my chest and I pat his head ." It's okay , I'm here ", I said calmly . After Wei Wuxian calm down , he give me a teeth smile ." Thanks (Y/N) and Jiang Cheng !", he thanks . I want to put him down but he wouldn't let me ." I want (Y/N) to hold me longer ", he said and I chuckle . I didn't know Jiang Cheng is jealous . I look down to see Jiang Cheng pouted ." What's wrong Jiang Cheng ?", I ask ." Nothing ", he pouted ." Jiang Cheng is jealous~", Wei Wuxian tease ." Shut up !", Jiang Cheng blush . I chuckle and pat his head ." I'll hold you after Wei Wuxian , alright ", I smiled and he blush .

 Time-skip 

After Wei Wuxian slept on my arms , I smile softly at the sleeping child ." (Y/N) do you like Wei Wuxian more than me ?", Jiang Cheng ask sadly . I notice the face he's making , just like how his father ignore him and treat Wei Wuxian better than him . I patted his head ," No , I like you both equally "." But who do you prefer !?", he ask . I think for a moment ," I can't pick one because you all are precious to me including Jiang Yanli ". He sit silent for a moment and it seems he dislike my answer ." I like you (Y/N) ", he confess ." I like you too ", I said ." No I mean I like you more than that !", he said seriously . I blink twice wondering what he mean ." I-I want you to be my wife ", he blush . I look down at Wei Wuxian ," I'm a maid I can't marry you , soon your parents will decid who you will be married to "." I don't care ! I want you !", he almost yell ." Shh Wei Wuxian is sleeping ", I shush him ." I-I want you to be by my side , I love you please ", he pleaded as his eyes began to tear ." He really is serious ", I thought . I gently put Wei Wuxian down and hug Jiang Cheng . His eyes widen and he hug me back .

" I'll be your wife when you grown up ", I said ." You promised ?", he ask with his eyes sparkle ." I promise ", I said and pull out my pinky . We do a pinky promised after this . His expression turn into a joyful face . I chuckle at him . He suddenly give me a peck on the lips ," You're my wife now and don't you fall for other man "." I'll listen to you Young Master Jiang Cheng ", I slightly bow .

Present 

I saw Jiang Cheng giving a lecture to Jin Ling . I feel bad for Jin Ling and I notice he is about to cry ." Jiang Cheng enough !", I yell . The 5 yrs old Jin Ling run to me and cried . I bend down and hold him up into my arms ." Dear you shouldn't be so hard on Jin Ling ", I said ." Why shouldn't I !? He couldn't hold an arrow . If I don't be strict he'll be so weak !", he yelled louder . I ignore his anger and smile at Jin Ling ." Jin Ling do you want to eat my homemade bun ?", I ask and he happily nodded . I walk away from Jiang Cheng with Jin Ling in my arms ." Hey I'm not done yet !", Jiang Cheng shouted .

I handed Jin Ling a bun and he ate it hungrily . After the death of his parents and betrayal of Wei Wuxian , he become like this ." He remind me of his mother Madam Yu ", I thought ." I really like your cooking mama ", he said happily . I smile sweetly at him . I allowed Jin Ling to call me his mother because I don't want him to be depress without a mother . After Jin Ling finish he fall asleep on my arms . I brush his hair with my fingers ." (Y/N) ", I heard Jiang Cheng call my name . I didn't turn my head . He sat down beside me and said ," I'm sorry "." You know you shouldn't put too much stress on Jin Ling , he's still a child ", I said softly . He look at Jin Ling sleeping face ." I need him to be strong enough to protect himself and the one he love . Is my teaching really wrong ?", Jiang Cheng ask . I sigh and turn to him ." You're teaching is not wrong but your altitude is the problem ", I pointed out ." How ?", he ask ." I dislike your grumpy altitude ", I said ." Y-You hate me !?", he ask with a shock look ." Yes ", I smirk . I know how worried he is and I chuckle ." I'm joking haha ", I laugh . Jiang Cheng face become red and his eyebrow furrow ." Don't joke about this ! It's not funny !", he almost yell .

Jin Ling move on my arms and I chuckle at how cute he is ." Do you remember when Wei Wuxian is sleeping on my arms and we made that promised ?", I ask ." Yeah . . .", he replied ." How long has it been ? The time when the 4 of us playing together ", I sigh as I recall the memory ." Do you still thinking about him ?", he ask angrily . I know he is jealous when I think of Wei Wuxian . I put my right palm on Jiang Cheng face and kiss his lips ." I only love you ", I smiled . He hug me and I hug back . Jin Ling open his eyes as he saw you 2 hugging . He join in the hug which surprise the adults ." You awake Jin Ling ", I said in surprise ." Jin Ling . . . I-I'm sorry ", Jiang Cheng apologize ." I forgive you uncle ", Jin Ling smiled . We chuckle and hug Jin Ling ." We loved you Jin Ling ", we both said ." I love you too uncle and mama ", he said happily .

Jiang Cheng you deserve to be single forever .
