As I mentioned in the introduction post (HERE), I've decided to keep track of the correct answers for the characters from the iPod's otome game "Shall we date?: My Sweet Prince" since I haven't been able to find a guide on the net. This post will be the walkthrough solution for Lambert

I must admit, I did love Lambert’s storyline. But then again, I love the classical tsundere character that initially dislikes you at first but then eventually warms up to you to the point where he’s heads over heels for you. Lambert’s the only character where you need to get all the correct answers before you get the Happy Princess endings, all the other candidates allow room for some error and you can still get the happy ending. So I was all that more determined to get his Happy Princess ending, which I must say was totally worth it!

Here are the photos associated with Lambert from his album:


His letters to you (which are sent to your mailbox by the end of the chapter) are as followed:


Despite there being two endings associated with each character, only the happy ending (which is referred to as Happy Princess) will be the only one meriting an event picture. The other ending (normal) does not have a picture linked to it. This is the picture rewarded to you if you get your Happy Princess ending with him. Summary of the ending will not be provided to avoid spoilers of this endearing ending


Depending on the answers you give to Lambert, you'll get one of the endings aforementioned. If you chose all the correct answers, you'll get the happiest ending. However, from what I've seen, you can still get the happiest ending even if you don't provide all the correct answers (aside from Lambert), but you will lose out on some of the event pictures 

In order to get the Happy Princess ending, you must select these answers (with some variation, but this is guaranteed):
Nod
He’s scary
Such penmanship
Try ad libbing?
Impossible!
Obey
Help with work
So cute
This is better
Isn’t it tiring?
Graceful Lotus
How do you feel?
Call a therapist
Even the palace?
Apologize anyway
Felt happy
Tell Lambert
Do you hate me?
Apologize first
Is there someone?
Sadly
Confess

That's the end of Lambert's route~! 

Please do not repost this without my permission or claim this as your own as it took me a while to get these answers!!
